/boot/initrd.img*should be removed from filesystem.squashfs

[Mantas Kriaučiūnas]

/boot/initrd.img*should be removed from filesystem.squashfs - now it takes about 7 MB space in CD, because it can't be compressed.

from #ubuntu-devel irc log:
Oct 09 15:02:10 Kamion tfheen: ubiquity does call update-initramfs, so removing /boot/initrd* is probably ok

I thought we were already doing this; are we only removing the kernel itself
and not the initramfs?

Colin, does ubiquity call update-initramfs unconditionally? i.e., is that
code already being thoroughly tested? Are we sure it does the right thing if
no initramfs already exists? If it's predictable and safe, we can do it,
otherwise it should wait until after the release.

I hope we're not removing the kernel! Ubiquity needs to copy it or the
resulting system won't boot.

Yes, it's called unconditionally. The most recent iteration of that code
landed on 16th September, so has been thoroughly tested in the beta.

Yes; I just tested with a version of ubiquity modified to remove the
copied initramfs just before calling 'update-initramfs -u', and it
worked fine.

Right, of course.

OK, let's go ahead then.

livecd.sh removes the initrd from the filesystem before compressing it now, so this should be fixed on the next daily (or manual) run.

[Mantas Kriaučiūnas (mantas)]

I found /boot/initrd.img.bak in 7.10 beta compressed filesystem - it seems livecd.sh doesn't remove /boot/initrd.img* :(

[Colin Watson (cjwatson)]

Moving to the livecd-rootfs package in Ubuntu.

[Colin Watson (cjwatson)]

Thanks for pointing out the stray .bak files; will be fixed in Intrepid.

[Launchpad Janitor (janitor)]

This bug was fixed in the package livecd-rootfs - 0.59

---------------
livecd-rootfs (0.59) intrepid; urgency=low

  [ Colin Watson ]
  * Remove /boot/initrd.img-*.bak (LP: #64887).

  [ Adam Conrad ]
  * Resurrect the proposed option for livecd.sh/BuildLiveCD, so
    we can build test images that include packages from proposed.
  * Build with updates and security by default, which is a no-op
    on development releases (where these suites are empty), but
    a necessity for point-release image building.
  * Copy bin/true from the chroot, not from the real root, so
    image builds for i386/lpia work on amd64, as intended.
