Thanks for the patch.  While it's a neat way to use the fallback,
I'm not happy with the hardcoding in the setup script, which goes
against the general design of the scripts (they are configured
using environment variables passed in from the schroot executable;
they don't dictate much policy themselves).

We can support it natively with "union-type=unionfs-fuse" in the
configuration file providing that we can update the mount options
to use fuse.  As a non-fuse user, is it possible to do the mount
with mount(8) rather than running "unionfs-fuse" directly?


Regards,
Roger
