Thanks. I'll test it later today.

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!
