I don't have anything specific about problems (other than using NFS
always makes things slower), I just wanted to point out that using NFS
for $HOME and having repositories in a subdirectory of $HOME with
working trees is surely a standard situation -- it is the whole point of
NFS that this is what is going to happen.

It worries me that this situation is being treated as second class
citizen by Bazaar.  Comments such as the above appear to bear out this
discrimination against NFS based usage :-(
