Bug Description

Binary package hint: klibc-utils

Using today's Karmic (20 aug 2009), with klibc-utils 1.5.15-1.

I removed the journal from my ext4 root partition (tune2fs -O ^has_journal).

This caused the system to become unbootable, because the initrd tries to mount the fs as ext2. Running fstype from klibc-utils shows ext2, and I guess that's the root cause. Adding rootfstype=ext4 to my kernel options in grub made the system boot.

This bug was fixed in the package klibc - 1.5.15-1ubuntu1

---------------
klibc (1.5.15-1ubuntu1) karmic; urgency=low

  * 20-signal-cleanup.patch: Cope with header changes in Linux 2.6.30.
  * 21-mntproc-definitions.patch: MNTPROC_MNT and MNTPROC_UMNT are no longer
    defined by the kernel. Hack around this by restoring the old
    definitions.
  * 22-ext4-no-journal.patch: Recognise ext4 filesystems without journals
    (LP: #416636).

It occurs that we should try and use blkid here not fstype, then we unify on a single filesystem detection library - blkid is in the initramfs already and *run in that script already*!

Yes, the same thought crossed my mind. I saw a rumour on a mailing list
somewhere that klibc upstream was already working on this, so we can
probably let them get on with it unless it takes too long. :-)

Do we use any other significant pieces of klibc anymore?
