How to ensure minimum versions of packages?
by Richard W.M. Jones 25 Mar '08

25 Mar '08

Maybe this is a kickstart question, I don't know. I've discovered that you can't specify versions of packages in the live CD kickstart file, eg the following doesn't work: %packages dhclient >= 4.0.0 For my application I really do need to specify minimum package versions, otherwise users will end up with a live CD that definitely won't work. Any suggestions about how to enforce this? Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-top is 'top' for virtual machines.

f7 livecd-creator cannot umount image after recent yum updates
by Skunk Worx 22 Mar '08

22 Mar '08

I ran yum updates two days ago and now the iso created by livecd-creator has a few issues. This is a Fedora 7 machine. 1) The tool complains that it cannot umount busy device : ... Building an initramfs at /boot/livecd-initramfs.img for kernel 2.6.23.15-80.fc7 FATAL: Module ide_cd not found. FATAL: Module usbhid not found. Done; initramfs is 4.3M. umount: /var/tmp/livecd-creator-iiLVNk/install_root: device is busy umount: /var/tmp/livecd-creator-iiLVNk/install_root: device is busy ioctl: LOOP_CLR_FD: Device or resource busy ... (otherwise completes successfully) 2) If I examine the final iso, mounting the squash image and then the os.img, I find the ext3 fs is inconsistent : mount -o loop /tmp/foo_sqsh/os.img /tmp/foo_img EXT3-fs: write access unavailable, cannot proceed. mount: wrong fs type, bad option, bad superblock on /dev/loop3, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so dmesg : loop: module loaded EXT3-fs: INFO: recovery required on readonly filesystem. EXT3-fs: write access unavailable, cannot proceed. # file /tmp/foo_sqsh/os.img /tmp/foo_sqsh/os.img: Linux rev 1.0 ext3 filesystem data (needs journal recovery) (large files) (If I copy the os.img out to a r/w location I can fsck.ext3 it) 3) The /etc/mtab in the os.img ends up errant so sysfs mount on boot of media complains : Remounting root filesystem in read-write mode: [ OK ] Mounting local filesystems: mount: sysfs already mounted or /sys busy mount: according to mtab, /sys is already mounted on /sys [FAILED] For now I am fixing the iso with a script : 1) copy out/fsck.ext3 the os.img file 2) remove the errant /etc/mtab 3) rebuild the squashfs with the new os.img using mksquashfs 4) rebuild the iso I thought this was obviously a kernel problem, but reverting to an older kernel on the build host did not fix it. TIA, John

Inserting custom kernel parameter to live CD
by Devrim GÜNDÜZ 20 Mar '08

20 Mar '08

Hi, I am building a live CD based on Fedora 8. I added this line to kickstart file: bootloader --append="selinux=0" --location=mbr I'm assuming that this will add a "selinux=0" line to grub. Am I wrong? I can't see this parameter in grub splash screen, and I still need to manually edit it to boot fine for some machines. Some of the users had a problem using my live CD, and using this parameter solves their problem (and yes, I don't care about selinux for this live CD). What is the way to add this parameter to kernel before booting?

Image options
by Gary Thomas 19 Mar '08

19 Mar '08

Are there image options other than squashFS for the LiveCD? I ask because building squashFS images on the PowerPC is excruciatingly slow :-( -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------

Build LiveCD for another architecture
by Gary Thomas 18 Mar '08

18 Mar '08

I'm trying to see if I can get the LiveCD tools to work in a pseudo-cross environment (using qemu as a helper). I have a lot of it working, down to the point where it's ready to install the actual packages. Then I get this error: Error creating Live CD : Unable to install: [('package filesystem-2.4.11-1.fc8.ppc is intended for a ppc architecture' I can't seem to figure out where this message comes from, nor how it is coming to this conclusion. n.b. I am running this on an x86, trying to force it to build for ppc. I've hacked things such that os.uname() always returns 'ppc' for the machine name which is how I got this far. -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------
