Comment 6 for bug 1427264

Serge - I've subscribed you to this bug in hopes that you could tell us if you expect any problems with making the change suggested at the bottom of comment #5 since I know you have a lot of experience in mount namespaces.

To summarize the problem, schroot doesn't handle /home/$USER being a mount point very well. If /home is recursively bound (rbind) into the schroot, then the recursive umount unmounts the /home/$USER outside of the schroot when tearing down the schroot session. I think recursively making /home a slave (rslave) fixes the problems but don't feel comfortable rolling out that change without getting another opinion.
