Targetting other file systems besides iso
by John (J5) Palmieri 06 Jun '07

06 Jun '07

At OLPC we need to support ext3 and jffs2 builds even more so than livecd isos. Since most of the process is the same up until the final image and bootloaders we would like to add this support into the livecd tools so that all fedora projects use one toolchain. The question is how can this best be accomplished? I think passing a --variant switch (i.e. --variant=jffs2) should switch the backend to generating the correct image. This also requires template support and the ability to select templates to write out based on the variant in the %post. For instance the olpc.fth file is read in by the openfirmware. For jffs2 builds we point to the nand on the XO machines. For ext3 we point to a USB disk. Also on ext3 we write out grub entries for use with standard machines and vitalization software like qemu. What would be the best way to add this support to the livecd tools? -- John (J5) Palmieri <johnp(a)redhat.com>

Support for custom configuration using python templates
by John (J5) Palmieri 16 May '07

16 May '07

This is the first in a bunch of OLPC needs I will be writing about on the list. It is super simple for me to hack up solutions that work for us but I would like to find a common solution that benefits all Fedora based projects. One of the things we need to for OLPC from the LiveCD creator is the ability to output configuration files from a template. We do this currently in Pilgrim and can do this in the LiveCD tools via the %post as shell scripts. This is pretty unwieldy and tends to be error prone with typos and missing character escapes causing sometimes hard to debug problems. A simple idea is to have standard template mechanism such as using pythons string substitutions. For example take the file /etc/issue. In shell we do this: cat <<EOF > $INSTALL_ROOT/etc/issue OLPC build $BUILD (stream $STREAM; variant $VARIANT) Kernel \r on an \m EOF It would be nice to have a template file which read something like: OLPC build %(build) (stream %(stream); variant %(variant)) Kernel \r on an \m and simply passed in a hash with substitutions from the livecd tools. Python templates or whatever templates is not really the issue here. What is the issue is defining a standard template format to use, defining how the tool finds the templates and defining how substitutions are specified. Any suggestions? I am willing to do the code myself but in the lack of any interest I'm going to end up creating a one off solution, so mucho input is desired. -- John (J5) Palmieri <johnp(a)redhat.com>

Intenet access with LiveCD?
by Jim Dever 11 May '07

11 May '07

Hi, I was excited to see the release of the Fedora LiveCD as I'm looking around at different distributions but for some reason I can't get it to see my internet connection at all. If anyone could point me in the right direction I'd appreciate it. NIC: Cnet PRO200WL PCI (not wireless) Router: Linksys RTP300 Output of ifconfig: eth0 Link encap:Ethernet HWaddr 00:80:AD:79:95:90 inet addr: 192.168.15.102 Bcast: 192.168.15.255 Mask: 255.255.255.0 inet6 addr: fe80::280:adiff:fe79:9590/64 Scope: Link UP BROADCAST MULTICAST MTU:1500 Metric: 1 RX packets: 13 errors: 170 dropped: 0 overruns: 0 frame: 0 TX packets: 0 errors: 10 dropped: 0 overruns: 0 carrier: 10 collisions: 0 txqueuelen: 1000 RX bytes: 2597 (2.5 KiB) TX bytes: 0 (0.0 b) Interrupt: 201 Base address: 0xec00 ----- I noticed that it says UP but not RUNNING. The Ubuntu LiveCD access the internet just fine so I know it's possible to MAKE it work. I just like to see it work before making room for a full install. I've used Linux before but it's been ages ago and before I had a NIC so I'm pretty new to this part. Any help would be appreciated! -- Jim

PowerPC support.
by David Woodhouse 30 Apr '07

30 Apr '07

At http://git.infradead.org/?p=users/dwmw2/livecd-ppc.git (git://git.infradead.org/~dwmw2/livecd-ppc.git) there's a set of patches which first introduces a little abstraction for the arch-specific configureBootloader() and createIso() functions, then implements the PPC version. 1. Allow mayflower path to be specified, to run from git tree 2, Remove syslinux from package lists; add it dynamically instead. 3. Move x86-specific functions (createIso, configureBootloader) into subclass 4. Only create isolinux/ directory in x86-specific configureBootloader() 5. Add PowerPC support, add pata_mpc52xx module to mayflower.conf The full patch is as follows... diff --git a/config/livecd-fedora-desktop.ks b/config/livecd-fedora-desktop.ks index 1ee6fba..780e201 100644 --- a/config/livecd-fedora-desktop.ks +++ b/config/livecd-fedora-desktop.ks @@ -23,7 +23,6 @@ services --enabled=NetworkManager,dhcdbd --disabled=network,sshd @dial-up @hardware-support @printing -syslinux kernel scim* diff --git a/config/livecd-fedora-kde.ks b/config/livecd-fedora-kde.ks index 20413b1..9aeceed 100644 --- a/config/livecd-fedora-kde.ks +++ b/config/livecd-fedora-kde.ks @@ -23,7 +23,6 @@ kernel dejavu-lgc-fonts setroubleshoot smolt -syslinux system-config-display xorg-x11-drivers diff --git a/config/livecd-fedora-minimal.ks b/config/livecd-fedora-minimal.ks index e8065b6..db52912 100644 --- a/config/livecd-fedora-minimal.ks +++ b/config/livecd-fedora-minimal.ks @@ -17,7 +17,6 @@ repo --name=a-extras-dev --baseurl=http://download.fedora.redhat.com/pub/fedora/ %packages bash kernel -syslinux passwd policycoreutils chkconfig diff --git a/config/livedvd-fedora-kde.ks b/config/livedvd-fedora-kde.ks index 1ed2f57..71aa122 100644 --- a/config/livedvd-fedora-kde.ks +++ b/config/livedvd-fedora-kde.ks @@ -23,7 +23,6 @@ kernel dejavu-lgc-fonts setroubleshoot smolt -syslinux system-config-display xorg-x11-drivers diff --git a/creator/livecd-creator b/creator/livecd-creator index a526b07..755e659 100755 --- a/creator/livecd-creator +++ b/creator/livecd-creator @@ -27,6 +27,8 @@ import traceback import subprocess import shutil import yum +import rpmUtils.arch +import rhpl import pykickstart.parser import pykickstart.version @@ -277,6 +279,178 @@ class LiveCDYum(yum.YumBase): cb.filelog = False return self.runTransaction(cb) +class InstallationArchPPC: + def __init__(self): + # For now we need anaconda-runtime, for bits like ofboot.b and mapping files. + # We could generate those ourselves though... + self.bootldr_package = ("yaboot","anaconda-runtime") + + def createIso(self, target): + """write out the live CD ISO""" + subprocess.call(["/usr/bin/mkisofs", "-o", "%s.iso" %(target.fs_label,), + "-hfs", "-hfs-bless", "%s/out/ppc/mac" %(target.build_dir), + "-hfs-volid", "%s" %(target.fs_label,), "-part", + "-map", "/usr/lib/anaconda-runtime/boot/mapping", + "-J", "-r", "-hide-rr-moved", "-no-desktop", + "-V", "%s" %(target.fs_label,), "%s/out" %(target.build_dir)]) + + def configureBootloader(self, target): + """configure the boot loader""" + + # Copy yaboot and ofboot.b in to mac directory + os.makedirs(target.build_dir + "/out/ppc/mac") + shutil.copyfile("%s/install_root/usr/lib/anaconda-runtime/boot/ofboot.b" %(target.build_dir), + "%s/out/ppc/mac/ofboot.b" %(target.build_dir,)) + shutil.copyfile("%s/install_root/usr/lib/yaboot/yaboot" %(target.build_dir), + "%s/out/ppc/mac/yaboot" %(target.build_dir,)) + + # Copy yaboot and ofboot.b in to mac directory + os.makedirs(target.build_dir + "/out/ppc/chrp") + shutil.copyfile("%s/install_root/usr/lib/anaconda-runtime/boot/bootinfo.txt" %(target.build_dir), + "%s/out/ppc/bootinfo.txt" %(target.build_dir,)) + shutil.copyfile("%s/install_root/usr/lib/yaboot/yaboot" %(target.build_dir), + "%s/out/ppc/chrp/yaboot" %(target.build_dir,)) + subprocess.call(["/usr/sbin/addnote", "%s/out/ppc/chrp/yaboot" %(target.build_dir,)]) + + os.makedirs(target.build_dir + "/out/ppc/ppc32") + shutil.copyfile("%s/install_root/boot/vmlinuz-%s" + %(target.build_dir, target.get_kernel_version()), + "%s/out/ppc/ppc32/vmlinuz" %(target.build_dir,)) + shutil.copyfile("%s/install_root/boot/livecd-initramfs.img" + %(target.build_dir,), + "%s/out/ppc/ppc32/initrd.img" %(target.build_dir,)) + os.unlink("%s/install_root/boot/livecd-initramfs.img" + %(target.build_dir,)) + + os.makedirs(target.build_dir + "/out/ppc/ppc64") + # FIXME: Need 64-bit kernel and initrd + + cfg32 = """ +init-message = "Welcome to the Fedora %(label)s LiveCD" +timeout=6000 + +""" %{"label": target.fs_label} + + stanzas = [("linux", "Run from image", ""), + ("runfromram", "Run from RAM - requires 1 GiB+", "live_ram")] + if os.path.exists("%s/install_root/usr/lib/anaconda-runtime/checkisomd5" %(target.build_dir,)): + stanzas.append( ("check", "Verify and run from image", "check") ) + + for (short, long, extra) in stanzas: + cfg32 += """ + +image=/ppc/ppc32/vmlinuz + label=%(short)s + initrd=/ppc/ppc32/initrd.img + read-only + append="ro quiet root=CDLABEL=%(label)s rootfstype=iso9660 %(extra)s" +""" %{"label": target.fs_label, + "short": short, "long": long, "extra": extra} + + cfgf = open("%s/out/ppc/ppc32/yaboot.conf" %(target.build_dir,), "w") + cfgf.write(cfg32) + cfgf.close() + os.makedirs(target.build_dir + "/out/etc") + cfgf = open("%s/out/etc/yaboot.conf" %(target.build_dir,), "w") + cfgf.write(cfg32) + cfgf.close() + + # FIXME.

Installation of Fedora 7 Test 4 F-6.93 Gnome CD
by Antonio Olivares 30 Apr '07

30 Apr '07

Dear all, I have installed F-6.93 Fedora 7 Test 4 onto a Toshiba laptop via LiveCD. Everything worked beautifully. Upon rebooting, things were looking okay until I saw the following: scsi: 1:0:0:0:0: CD-ROM HL-DT-ST DVDRAM GMA-4082N dev-mapper: ioctl: 4.11.0-ioctl (2006-10-12) initialised: dm-devel(a)redhat.com mount: could not find filesystem '/dev/root' setuproot: moving /dev/ failed: no such file or directory setuproot: error mounting /proc: no such file or directory setuproot: mounting /sys: no such file or directory switchroot: mount failed: no such file or directory Kernel panic - not syncing: Attempted to kill init! Looks like something did not go well while it appeared everything did. I should first check with a rescue cd or install dvd to see that it finds valid filesystem and then report back.

LiveCD Failure - Can't Stat stage2_eltorito
by Paul Dubinsky 30 Apr '07

30 Apr '07

Howdy, Folks, This is my first try at creating a LiveCD on a newly installed FC6_64 and I'm having a problem. Using livecd-creator as in: livecd-creator --repo=c6,file:///var/www/html/repo/core --repo=lcd6,file:///root/base_packages --package=fedora-livecd-gnome --repo=e6,http://download.fedora.redhat.com/pub/fedora/linux/extras/6/i386 --fslabel=My-Fedora-LiveCD-1 I get a failed exit with the msg: /usr/bin/mkisofs: Uh oh, I cant find the boot image 'boot/grub/stage2_eltorito' ! Earlier: /sbin/setfiles: error while labeling files under /var/named/chroot/var/run/dbus /bin/cp: cannot stat `/var/tmp/livecd-creator/build-tmp-oMLql/install_root/usr/share/grub/i386-redhat/stage2_eltorito': No such file or directory Any suggestions about where to look for the problem? Thanks, Paul -- ============================================= "Disease can be cured. Dakar, however, is an addiction. Addictions are for life." =============================================

Fedora 7 Test 4 GNOME based i386 Live CD report
by Rahul Sundaram 30 Apr '07

30 Apr '07

Hi Just installed the F7 T4 GNOME based i386 live cd and here are some of my observations after playing with it for a day. * You do not need to accept the EULA anymore. It just has a pointer to the wiki link instead of including the text. * Smolt integration UI is good and works well. Noticed that it said it would update the profile automatically on a monthly basis. My test system profile is http://smolt.fedoraproject.org/show?UUID=492900d9-5ee0-441c-9792-fc2ecc86aa… * Look and feel is good. Flying high theme with Mist based icon set. * Firefox and Evolution are the default panel applications but seem to be using the old Blue Curve icons. * Network manager (nm-applet) is enabled by default * Blog, stock ticker, bittorrent and gparted applications installed by default * fast user switcher applet is on the panel by default and shows up on the lock screen. too. * Multiple locales and input methods available by default * Abiword does not crash on startup anymore. gnumeric is also available but we are missing a small presentation program to complete this sort of mini office suite. * Beagle is installed by default and replaces gnome-search-tool on the UI like the previous release. Might be better to keep these entries separate. * gThumb and GIMP are available by default but not f-spot. * Pigdin has replaced Gaim. Has new icons and a better interface. * Wodim has replaced cdrecord. cdrecord is a symlink to wodim and works as expected. * New application, system-config-selinux is available under administration. Looks pretty comprehensive. SELinux boolean configuration has been removed from system-config-securitylevel and is now available in this tool. Title says "system-config-selinux.py" instead of just "system-config-selinux" which is a minor wart in the UI. * Places and /home/<user> is filled by default folders for documents, video etc. Might look less cluttered if those default folder were under a common parent. /home/<user>/personal/<default folders> for example. * Preferences menu is organized into multiple categories now. The central control panel that GNOME includes is disabled by default (upstream inherited) but can be enabled using alacarte. Menu editor is a entry now in the preferences menu. * Yum is faster. Pirut and Pup UI does not appear to hang anymore. * About Fedora menu entry uses old wordings and says Fedora people instead of Planet Fedora as we have agreed upon now for consistency. * nautilus-open-terminal extension was not installed by default unlike previous live cd releases. * SCIM input icon doesnt show up on the system tray unlike the previous test release. Default is showing on demand but setting it to show always does not make it show up on the system tray. * nautilus has crashed more than once during login including the previous test releases with some vague bonobo error which I did not note down. Anyone else seeing this? * Turning on desktop effects immediately makes it crash Xorg * shutdown entry showed up twice as first and last entries in the system menu just once. Rest later, Rahul

Inheritance
by John (J5) Palmieri 27 Apr '07

27 Apr '07

In the pilgrim tool it is fairly easy to inherit from "stream" files and just expand a base image into a newer image. This means I can create a base description for an image, with all the required rpms and %post processing and then define another image description which adds more rpms and does more post processing. We can even override hooks and files in the child description. For instance our liveCD SDK has added gnome packages but does not download the ondisk html library to save space. This allows me to make changes to the base image which is automatically reflected in the livecd image builds. The real reason we need this is for country builds. I know that the livecd tools already have the ability to take an iso and add to it but I also need the ability to do a build from scratch. First can the current kickstart file format handle this and second how can we support this if it does not? -- John (J5) Palmieri <johnp(a)redhat.com>

I forgot to mention that my program can also dump strong components (ie dependency cycles). Here are the results: ConsoleKit-libs <-> MAKEDEV <-> SysVinit <-> coreutils <-> dbus <-> device-mapper <-> device-mapper-libs <-> e2fsprogs <-> e2fsprogs-libs <-> initscripts <-> krb5-libs <-> libselinux <-> libxml2-python <-> logrotate <-> mcstrans <-> module-init-tools <-> net-tools <-> openssl <-> pam <-> psmisc <-> python <-> python-libs <-> shadow-utils <-> sysklogd <-> udev <-> util-linux aspell <-> aspell-en chkfontpath <-> xorg-x11-xfs fast-user-switch-applet <-> gnome-panel fedora-logos <-> redhat-artwork festival <-> festvox-slt-arctic-hts firstboot <-> system-config-keyboard gnome-python2 <-> gnome-python2-bonobo <-> gnome-python2-gnomevfs hal <-> hal-info mono-web <-> mono-winforms perl <-> perl-devel rpm <-> rpm-libs xorg-x11-drv-evdev <-> xorg-x11-drv-keyboard <-> xorg-x11-drv-mouse <-> xorg-x11-drv-vesa <-> xorg-x11-drv-void <-> xorg-x11-server-Xorg yp-tools <-> ypbind While most are small and easy to explain, there are a few horrible ones, like the one involving ConsoleKit-libs
