When this saga first started an `ls -l /net/bix' showed a corrupted dentry
for /net/bix/usr. It was determined that this was SELinux-related. Fixes were
made and that no longer occurs.

Now, treading on /net/bix/usr/src does not cause bix:/usr/src to be mounted
at /net/bix/usr/src. Without git-nfs that mount does occur.

The present behaviour is unchanged if /selinux/enforce is set to 0.

Nope.
