[Bug 810700] Re: Oneiric Installer crashes "OSError: [Errno 21]"

[Mario Limonciello]

This happened because of the /var/run -> /run transition in progress.
/var/run used to be a directory and is now a symlink.

Partman creates /target/var/lock and /target/var/run as soon as the
disks are formatted.  When the file copy routine gets around to these
directories, it assumes they were files or symlinks and tries to unlink
them, but fails because they're directories.

I've committed a fix to trunk to rmdir the directories when this
happens, but another way to fix it would be to remove the code in
partman from creating /target/var/lock and /target/var/run in the first
place.
