auto-biarch (x86_64 + i686) LiveDVD patch + ISO
by Jan Kratochvil 01 Jan '11

01 Jan '11

Hi, finally created a LiveDVD ISO automatically booting x86_64 OS on x86_64 (and i686 otherwise). Regular users will not notice there exists any new arch while they will benefit from the full performance of their PC: http://people.redhat.com/jkratoch/x86bilive-2009062000.tar.gz (71KB) It uses live_dir=LiveOS-x86_64 vs. live_dir=LiveOS-i686 to boot the image. The syslinux patch provides "default-{x86_64,i386}" keywords in isolinux.cfg. livecd-iso-to-disk is not patched/compatible with such image. livecd-creator should create such ISO on a single run, not by merging the output of two livecd-creator runs by a 3rd party app. Regards, Jan Reasons: * I still did not understand why I have to carry with me two media - both x86_64 and i386 - when all the data perfectly fit on a single media. * Why I have to try to boot x86_64 first to find out if the specific machine is x86_64? Even common programmers do not know it, "Windows XP works here". * The OS must "just work", it must be fun and easy. Requiring a special technical decision before even starting the OS download is a showstopper. * Checked that a regular user will on http://fedoraproject.org/get-fedora still download terrible performance degradation of 32-bit OS although her hadware is in 70%-95%(?) of cases x86_64. x86_64 is here for 6 years now. * Arguing x86 may be faster than x86_64... I did not find any such case, x86_64 is a more modern arch (more registers, PIC for free, better ABI). We already hit the 2GB address space limitations. x86_64 is the future. * All the friends of mine have 8Mbit+ ADSL and TB disks downloading many DVD disks so some several more hundreds of MB are not something to notice. mkisofs -f -J -r -hide-rr-moved -hide-joliet-trans-tbl -V Fedora-11-x86bi-Live -o ../x86bilive.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-info-table -boot-load-size 4 . mount -r -o loop Fedora-11-x86_64-Live.iso x86_64/ mount -r -o loop Fedora-11-i686-Live.iso i686/ x86bilive: total 4 lrwxrwxrwx 1 root root 13 2009-06-18 21:10 GPL -> ../x86_64/GPL lrwxrwxrwx 1 root root 14 2009-06-18 21:11 LiveOS-i686 -> ../i686/LiveOS/ lrwxrwxrwx 1 root root 16 2009-06-18 21:10 LiveOS-x86_64 -> ../x86_64/LiveOS/ lrwxrwxrwx 1 root root 16 2009-06-18 21:10 README -> ../x86_64/README drwxr-xr-x 2 root root 4096 2009-06-20 21:44 isolinux/ x86bilive/isolinux: total 184 lrwxrwxrwx 1 root root 30 2009-06-18 21:13 boot.cat -> ../../x86_64/isolinux/boot.cat lrwxrwxrwx 1 root root 31 2009-06-18 21:17 ii686 -> ../../i686/isolinux/initrd0.img -rw-r--r-- 1 root root 14336 2009-06-20 21:45 isolinux.bin -r--r--r-- 1 root root 1411 2009-06-20 21:44 isolinux.cfg lrwxrwxrwx 1 root root 33 2009-06-18 21:13 ix8664 -> ../../x86_64/isolinux/initrd0.img lrwxrwxrwx 1 root root 28 2009-06-18 21:17 ki686 -> ../../i686/isolinux/vmlinuz0 lrwxrwxrwx 1 root root 30 2009-06-18 21:13 kx8664 -> ../../x86_64/isolinux/vmlinuz0 lrwxrwxrwx 1 root root 29 2009-06-18 21:13 memtest -> ../../x86_64/isolinux/memtest lrwxrwxrwx 1 root root 32 2009-06-18 21:13 splash.jpg -> ../../x86_64/isolinux/splash.jpg -r--r--r-- 1 root root 159888 2009-06-20 20:48 vesamenu.c32 isolinux.cfg: default vesamenu.c32 timeout 100 menu background splash.jpg menu title Welcome to Fedora-11-x86bi-Live! menu color border 0 #ffffffff #00000000 menu color sel 7 #ffffffff #ff000000 menu color title 0 #ffffffff #00000000 menu color tabmsg 0 #ffffffff #00000000 menu color unsel 0 #ffffffff #00000000 menu color hotsel 0 #ff000000 #ffffffff menu color hotkey 7 #ffffffff #ff000000 menu color timeout_msg 0 #ffffffff #00000000 menu color timeout 0 #ffffffff #00000000 menu color cmdline 0 #ffffffff #00000000 menu hidden menu hiddenrow 5 label linux0 menu label x86_64 Boot kernel kx8664 append initrd=ix8664 root=CDLABEL=Fedora-11-x86bi-Live rootfstype=auto live_dir=LiveOS-x86_64 ro liveimg quiet rhgb menu default-x86_64 label check0 menu label x86_64 Verify and Boot kernel kx8664 append initrd=ix8664 root=CDLABEL=Fedora-11-x86bi-Live rootfstype=auto live_dir=LiveOS-x86_64 ro liveimg quiet rhgb check label linux1 menu label i686 Boot kernel ki686 append initrd=ii686 root=CDLABEL=Fedora-11-x86bi-Live rootfstype=auto live_dir=LiveOS-i686 ro liveimg quiet rhgb menu default-i386 label check1 menu label i686 Verify and Boot kernel ki686 append initrd=ii686 root=CDLABEL=Fedora-11-x86bi-Live rootfstype=auto live_dir=LiveOS-i686 ro liveimg quiet rhgb check label memtest menu label Memory Test kernel memtest label local menu label Boot from local drive localboot 0xffff --- /dev/null 1 Jan 1970 00:00:00 -0000 +++ defaults.patch 20 Jun 2009 20:10:46 -0000 @@ -0,0 +1,175 @@ +--- syslinux-3.75-orig/com32/menu/Makefile 2009-04-16 06:42:14.000000000 +0200 ++++ syslinux-3.75-defaults/com32/menu/Makefile 2009-06-20 19:21:32.000000000 +0200 +@@ -24,7 +24,7 @@ MODULES = menu.c32 vesamenu.c32 + TESTFILES = + + COMMONOBJS = menumain.o readconfig.o passwd.o drain.o printmsg.o colors.o \ +- background.o refstr.o execute.o ++ background.o refstr.o execute.o verify_cpu.o + + all: $(MODULES) $(TESTFILES) + +--- syslinux-3.75-orig/com32/menu/menu.h 2009-04-16 06:42:14.000000000 +0200 ++++ syslinux-3.75-defaults/com32/menu/menu.h 2009-06-20 19:21:32.000000000 +0200 +@@ -224,4 +224,9 @@ void execute(const char *cmdline, enum k + /* drain.c */ + void drain_keyboard(void); + ++/* verify_cpu.S */ ++#if defined(__i386__) || defined(__x86_64__) ++int verify_cpu(void); ++#endif ++ + #endif /* MENU_H */ +--- syslinux-3.75-orig/com32/menu/readconfig.c 2009-04-16 06:42:14.000000000 +0200 ++++ syslinux-3.75-defaults/com32/menu/readconfig.c 2009-06-20 20:23:24.000000000 +0200 +@@ -656,11 +656,22 @@ static void parse_config_file(FILE *f) + m->parent_entry->displayname = refstr_get(m->title); + } + } +- } else if ( looking_at(p, "default") ) { +- if (ld.label) { +- ld.menudefault = 1; +- } else if (m->parent_entry) { +- m->parent->defentry = m->parent_entry->entry; ++ } else if ( looking_at(p, "default") ++#if defined(__i386__) || defined(__x86_64__) ++ || looking_at(p, "default-i386") ++ || looking_at(p, "default-x86_64") ++#endif ++ ) { ++#if defined(__i386__) || defined(__x86_64__) ++ if (!

livecd-creator creates ISO without /home
by Martin Dengler 09 Sep '09

09 Sep '09

Hi, I'm getting a .ISO without a /home despite the filesystem rpm being installed, and I'd really appreciate any tips on debugging this or hints as to how this might happen. This is with the example .ks and I can get livecd-creator to work on a number of other machines. If I chroot and install the same filesystem rpm again (--force of course, since it's already installed), I do get a /home. I'm running: $ setarch i586 sudo livecd-creator --skip-compression --cache=../cache -t /home/mtd/xo-soas/images -c /usr/share/doc/livecd-tools-024/livecd-fedora-minimal.ks on a machine like: # uname -r Linux benderxxx 2.6.29.4-167.fc11.x86_64 #1 SMP Wed May 27 17:27:08 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux and I'm getting a filesystem like: http://people.sugarlabs.org/~mtd/soas-xo1/livecd.ext3_listing The output of the livecd-creator command is: http://people.sugarlabs.org/~mtd/soas-xo1/livecd.buildlog Any help much appreciated.

Problem with bootloader options in kickstart file
by harry.devine＠faa.gov 31 Jul '09

31 Jul '09

I have livecd-tools version 013 installed on a Fedora 8 PC. I'm trying to modify my kickstart file to blacklist a module on the LiveCD that I am creating, but it isn't working. I'm adding the following to my kickstart file: bootloader --timeout=5 --append="blacklist=iTCO_wdt" When the CD boots I get the timeout value counting down from 5, and when I hit Tab to look at the kernel options on the command line, all I have is "rhgb quiet" as stated in the documentation. As a test, I tried putting "apci=force" as the kernel parameter and that isn't there either. I can manually enter "blacklist=iTCO_wdt" on the command line and that works, but the --append option seems to do nothing at all. Is this broken in this version? I know some may say "upgrade to F11" or something like that, but that's not really possible for us at this time. We're working towards that, but I'd like to be able to blacklist that module during the LiveCD creation. Thanks, Harry

Custom LiveCD
by Diego A. Fons 29 Jul '09

29 Jul '09

Hi, I'm making my own LiveCD using Fedora's tools (livecd-creator) as explain in the Wiki [1]. My question is if it is possible to install software ready to run in the LiveCD. I mean, you boot the LiveCD and you are able to run the software without installing it. The software is not a RPM, it's a software I've made. Is it possible? and How can I add this software to the LiveCD image? Best regards, Diego A. Fons. [1] http://fedoraproject.org/wiki/How_to_create_and_use_Fedora_LiveCD

unbootable rawhide images
by Sebastian Vahl 28 Jul '09

28 Jul '09

Hi. Are there some issues known that current live images with livecd-creator from git are unbootable atm? With my images I have the problem that the booting stops after the squashfs message of the kernel (eg. here from VirtualBox: http://img525.imageshack.us/img525/2016/livecdcreatorrawhidenob.png) This also affects the "Verify and boot" option.

Increasing Root Size on Fedora 11 Live USB Stick
by tobby luccas 24 Jul '09

24 Jul '09

Hello! I am new to using Fedora 11 Live on a usb stick and am wondering if there is a relatively simple way to increase the size of the root partition on the stick after it has been installed using the Fedora-Live_USB Creator utility v3.6.7. I used the x86-64 live image to create the stick. Or alternately recreate the stick, but with more space going to the root partition. Also, is there a document somewhere, or a thread, which provides an overview of the file system created on the usb stick and also how persistence works? I set the 8 GB stick up with 4 GB of persistence, but this seems to mostly have ended up in the /tmp directory and when I try ro install software to its appropriate place on the system, I have quickly run out of space eventhough I haven't installed anywhere near 4GB of software. I would appreciate any help which someone may be able to offer. Thanks!

Fedora live usb:- storing data on the remaining space on the USB
by kala 20 Jul '09

20 Jul '09

Dear friends. Last time when i have used fedora 9 on a live usb it gives me an ability to mount the same usb (which i used for booting) and store data onto it , however i skipped FC10 and now when i am using FC11 I am unable to do so any more, is there a way to use the same usb drive for storing data ( this enables to share data from systems to systems and OS to OS). kala bharath

Booting Fedora 11 live CD over HTTP
by Pravin 18 Jul '09

18 Jul '09

Hi, I am working on booting Fedora 11 live CD (Fedora-11-i686-Live.iso) over HTTP with use of httpfs. The reason behind choosing httpfs is that, it will work if you have web access. and Entire ISO file is not downloaded at one go. Only the parts which are needed are downloaded, which puts less pressure on memory. This is done with partial success. Fedora 11 works in Single user mode without any problems, but it gives ext4-fs related errors on switching to run level 3 or 5. Following is the method followed. -- Added the httpfs, fusermount and kernel modules (to support networking fuse) to initramfs. -- Added a new script called "bin/mount_http_iso.sh" which does following --- Enable networking (by inserting kernel modules). Currently, modules for only few network cards are added but new card can be easily added. --- Setup networking (kernel parameter "ip" is used). --- Get the location of ISO (kernel parameter "httpfs" is used). --- Mount the ISO as file (using "httpfs" command and fusermount). --- Mount the ISO file as iso9660 filesystem using loopback option. -- Modified the "sbin/real-init" script to call "mount_http_iso.sh" when httpfs boot parameter is present. "/bin/plymouthd" had to be disabled as it was somehow freezing the boot process. I am not sure of reasons behind it, but fedora 11 boots over http if following line in "init" script is commented out and it does not boot when this line is there. {{{ #daemonize --ignore-missing /bin/plymouthd }}} If run level is switched for from single user mode run level 3 by executing "init 3" from single user mode, following ext4-fs related errors are thrown. Any hints on cause of these errors will be helpful. Starting Bluetooth services: [ OK ] EXT-4-fs error (device dm-0): ext4_find_entry: reading #13191 offset 0 /etc/rc.d/rc : line 100 : /etc/rc3.d/S80sendmail: Input/output error EXT4-fs error (device dm-0): __ext4_get_inode_loc: unable to read inode block - inode=9642, block=827 After disabling following startup scripts in runlevel 3, Fedora does reaches multiuser login prompt but enter key is shown on console as "^M" hence login can-not be done :-( the modified real-init script is available at http://rom.etherboot.org/share/pravin/BKO/pxeknife/red_hat/fedora_11_live_c… The entire setup for testing the process of booting Fedora 11 is available at http://rom.etherboot.org/share/pravin/BKO/pxeknife/red_hat/ gpxe image to automatically for automatic booting over fedora 11 can be downloaded at http://rom.etherboot.org/share/pravin/BKO/ You can also refer to the following page which contains detailed documentation of the problems faced and solutions tried. My apologies if you find this page little dis-organized. It was created for personal reference. http://etherboot.org/wiki/soc/2009/pravin/journal/fedora11bko Any feedback/criticism/help and hints on getting fedora boot over HTTP will be welcome :-) I hope that this work will be found useful. -- Pravin http://rom.etherboot.org/share/pravin/BKO/
