kernel BUG at /build/buildd/linux-2.6.34/ubuntu/aufs/f_op.c:84!

[Kees Cook]

Trivial use of aufs doesn't crash, but trying to start up an aufs directory from schroot fails, and then the umount cannot even clean it up. During set up, it's /etc/schroot/setup.d/22nssdatabases that finally triggers the issue.

Hi Kees,

This looks like a duplicate of bug 587888 which is buggering up the Maverick desktop CD's from booting. For now I'm going to mark this a duplicate of bug 587888. However, as you're able to reproduce at the moment, we might need your assistance with testing. We'll post any requests to the master bug 587888. Thanks.
