[Bug 672177] [NEW] libc6 upgrade causes umount to fail on shutdown

[Launchpad Bug Tracker]

You have been subscribed to a public bug by ingo (ingo-steiner):

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!
