Another "Stateless" project for Fedora
by Krzysztof Kozlowski 28 Jan '05

28 Jan '05

Hello I wish to introduce my own little "stateless" (actually a kind of NFS-readonly-root) project : http://acn.waw.pl/koziol/projekty/fedora_nfs_readonly_root/index.html I wanted to do this completely from the scratch - to learn something :). Maybe it will be interesting for you :). The goal is to boot Fedora Core 3 by PXE and mount root from NFS (readonly). I've prepared some scripts to create the "initrd.img" for booting. They were designed to work on FreeBSD (which is a server in my case), but I've tested them on Fedora Core 3. Currently only those scripts are published (I think it's the most difficult part) and documentation for initrd.img and the booting process (*only in Polish*, sorry my English is awfull :) ). In the future I will publish another part of scripts - how to prepare NFS server for serving NFS-root... Hope my work will be usefull for someone Krzysztof Kozłowski

Harris <mharris(a)redhat.com> 6.8.1.902-6 - Added xorg-x11-6.8.1.902-lnxLib-tmpl-sharedlibreq-fixes.patch to fix many missing library dependancies in lnxLib.tmpl, detected by examining the build log of a "with_bail_on_undef_syms" build. - Disabled with_bail_on_undef_syms, after determining that there is a bit of work that needs to be done upstream first in order for us to expect X to fully build with these linker options. * Mon Jan 24 2005 Mike A. Harris <mharris(a)redhat.com> 6.8.1.902-5 - Removed dead unused i810 update patch. - Enabled with_bail_on_undef_syms, to do a test build.

DBUS features
by Trever L. Adams 27 Jan '05

27 Jan '05

My examples are going to be somewhat bad, but please see through them for the reasoning and the necessity of these features. 1) We need a way to know if someone, using DBUS, is logged in either in a terminal or an X session. Think of a situation where you have a piece of software that needs to do tasks from time to time (changing of runlevels is likely). You want to automate this, or at least be able to tell the machine to do it. However, this process should wait (or the shell script that does all the running) until no one is logged in. Yes, yes, who and w might provide that, but I find this a cleaner solution. 2) We need a way to know if some critical process, such as up2date, is being run at shutdown and allow the app, as long as it response every X amount of time (2 minutes or so) to continue to run. Think of a network environment and someone is doing an up2date via cron or ssh. Someone finishes using the computer and turns it off. This should pause, in a test or graphical shut down, showing a list of such processes. It should not execute any shut down sequences until this list is empty, or they programs all cease to respond. These processes should notify DBUS, that they need to complete and that they have completed, and have an event handler to respond to DBUS. I have a few ideas about the VNC features as well, but those will come later. What do you all think? Is this possible (I am fairly sure it is)? Is it a good thing... I think so? Trever Adams P.S. In the thread where I used HAL in the place of DBUS, someone pointed out #1 is probably fairly simple, and the tone made it sound that it may not be a good idea in FC, this is fine if it is the case, but the functionality and core pieces for #2 should still be looked at. -- "Walking on water and developing software to specification are easy as long as both are frozen." --Edward V.

Hi All, I was looking to evaluate Stateless Linux. Searching the archives of this list didn't turn up anything, and Google really only came up with the announcements in September. I see that the rpms (http://people.redhat.com/dmalcolm/stateless/) haven't been updated in a while, nor are they in the development tree - Is there still work being done on this, has it changed names, etc? Thanks, Erik. -- e r i k w i l l i a m s o n erik(a)cpsc.ucalgary.ca system admin . department of computer science . university of calgary

Fedora and Xen: A Quick Start Guide
by Jeremy Katz 27 Jan '05

27 Jan '05

As some people have noticed, Xen is now available from the Fedora development repository. More information on Xen itself can be found at http://www.cl.cam.ac.uk/Research/SRG/netos/xen/index.html. We're following the -unstable Xen tree at the moment which does occasionally lead to things being broken but also lets us track a lot of the more interesting work going on there. Since setting up to run Xen isn't entirely straight-forward, here's a run-through of what should work for setting up a single Xen guest running the Fedora development tree. To run xen on a system pulling strictly from the Fedora devel repository, all of your deps should get satisfied automatically. But, they are explicitly * mkinitrd 4.2.0 * python 2.4 * python-twisted * Using grub as your boot loader [1] * Probably something on the order of 256 MB of RAM with the default setup [2] Then, you should be able to install the xen and kernel-xen0 packages. Once this is done, you should have an entry set up in your grub.conf to boot the xen0 kernel. Now, reboot into your new xen0 kernel [3] Once you've rebooted, you should be running in the dom0 kernel. You'll see a slightly scary looking warning about TLS during bootup and how to disable it, but it shouldn't make things too bad. Then, if you start xend with 'service xend start', you should be able to run 'xm list' and see your domain running. Now, we want to set up a simple base Fedora system. First, you'll want to install the kernel-xenU package (unfortunately, the kernel for your guest domain must currently be kept outside of the guest itself). Next, let's create a file to use as the backing for our Fedora install. For example purposes, I'll create one of a size of 1 GB. dd if=/dev/zero of=/root/fedora.img bs=1M count=1024 Now, create an ext3 filesystem on this image. mke2fs -F -j /root/fedora.img You should now be able to mount your new temporary rootfs on a temporary mountpoint, say /mnt mount -o loop /root/fedora.img /mnt Now, we can install whatever basesystem we want into this chroot. Make sure that your yum configuration points to a valid repository. Then, decide what group(s) you want to install. I'd recommend starting with Base (or for the space constrained, Core, but this is more difficult). Then, run yum --installroot=/mnt -y groupinstall Base Now, go get some coffee and have a snack. It's going to take a little while :-) Come back and if everything went okay, you'll have a minimal install in /mnt. Now, for the ugly part, we need to set up some basic bits on the filesystem that have to be different for xen right now. These include a) creating some required device nodes in /dev since we're not using an initrd and b) setting up an /etc/fstab for i in console null zero ; do MAKEDEV -d /mnt -x $i ; done For the /etc/fstab, something simple like the following should work /dev/sda1 / ext3 defaults 1 1 none /dev/pts devpts gid=5,mode=620 0 0 none /dev/shm tmpfs defaults 0 0 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 Do any other configuration you want to on the filesystem and then unmount it [4] umount /mnt{/proc,} Now, we just have to create a config file and you should be good to go. I go for a very simple config file like the following which is /etc/xen/rawhide on my machine [5] kernel ="/boot/vmlinuz-2.6.10-1.1103_FC4xenU" memory = 64 name = "rawhide" nics = 1 disk = ['file:/root/fedora.img,sda1,w'] root = "/dev/sda1 ro" Now, create a new domain with 'xm create -c rawhide' and off it goes. At the end, you should see the login prompt at which point you can login as root and begin playing around some. This is pretty early and rough, but it's enough to starting playing with. The next step (for me :) is getting to where you can do actual installs in a Xen guest environment and then being able to boot kernels which are on the guest's filesystem. Jeremy [1] This is required because you actually boot the Xen hypervisor and it then starts the Linux kernel. It does this using the MultiBoot standard [2] You can conceivably get by with less, but you'll have to reduce the dom0_memory line in /boot/grub/grub.conf. The 130000 for dom0 is currently hard-coded by mkinitrd (will get fixed before too long) and can go a little lower. Also, the Xen hypervisor ends up requiring ~ 32 MB. Plus any memory for your unprivileged guests. [3] Note, you may need to disable rhgb and switch to using runlevel 3. There are conflicting reports about X working; I haven't tried [4] And /proc under it, since /proc has to get mounted for a lot of things to get done right. But yum figures that out [5] Substitute /boot/vmlinuz-2.6.10-1.1090_FC4xenU with the xenU kernel you installed. Additionally, the device sda1 listed here as the disk is related to the /etc/fstab you created above

HAL features needed
by Trever L. Adams 27 Jan '05

27 Jan '05

My examples are going to be somewhat bad, but please see through them for the reasoning and the necessity of these features. 1) We need a way to know if someone, using HAL, is logged in either in a terminal or an X session. Think of a situation where you have a piece of software that needs to do tasks from time to time (changing of runlevels is likely). You want to automate this, or at least be able to tell the machine to do it. However, this process should wait (or the shell script that does all the running) until no one is logged in. Yes, yes, who and w might provide that, but I find this a cleaner solution. 2) We need a way to know if some critical process, such as up2date, is being run at shutdown and allow the app, as long as it response every X amount of time (2 minutes or so) to continue to run. Think of a network environment and someone is doing an up2date via cron or ssh. Someone finishes using the computer and turns it off. This should pause, in a test or graphical shut down, showing a list of such processes. It should not execute any shut down sequences until this list is empty, or they programs all cease to respond. These processes should notify HAL, that they need to complete and that they have completed, and have an event handler to respond to HAL. I have a few ideas about the VNC features as well, but those will come later. What do you all think? Is this possible (I am fairly sure it is)? Is it a good thing... I think so?

Sometimes I feel RHEL does not use yum either, so yum was not an option either.
