[Bug 672177] Re: libc6 upgrade causes umount to fail on shutdown because init cannot be restarted

[NoOp]

@Clint: it's back. On Natty 11.04 I am getting unclean inodes again.  I notice a single inode in dmesg after every boot:
$ cat /var/log/dmesg.0 | grep orphan
[    4.470372] EXT4-fs (sda1): orphan cleanup on readonly fs
[    4.470443] EXT4-fs (sda1): ext4_orphan_cleanup: deleting unreferenced inode 2228229
[    4.470538] EXT4-fs (sda1): 1 orphan inode deleted

So I ran the test:

$ sudo -i
# apt-get install --reinstall libc6 && shutdown -r now

 on reboot:
$ dmesg | grep orphan
[   13.408854] EXT4-fs (sda1): orphan cleanup on readonly fs
[   13.408928] EXT4-fs (sda1): ext4_orphan_cleanup: deleting unreferenced inode 541072

Bug description:
  On a clean install of Ubuntu 10.04.1, after upgrading the offer libc6
  upgrade, on the next reboot the root fs can't be properly unmounted
  (mount: / is busy). This causes fsck to run on boot and of course some
  minor issues with the filesystem. This might not be a problem with
  libc6 itself, but a side effect of upgrading in combination with some
  other package (I suspect the init process, so I guess upstart).

  The fsck run, and the orphaned inodes it finds are holding me back
  from installing this on a new server - especially since this already
  happens on a clean install of 10.04.1!
