Ah, that makes sense.  We had one report of schroot no longer
working with gdm, but it wasn't clear why.

We try to keep what's mounted from the host as minimal as possible,
and in this case it's specific to a single application.  It's not
required for any use case other than running X applications, so I'd
rather keep it out of the default config.

I am, however, collecting custom setup scripts and configurations
for specific uses in a new contrib directory which I will install
under /usr/share/doc.  I can refer to this in README.Debian and/or
the upstream docs and include the above mount options for gdm if
that sounds OK.  Maybe as a "desktop" profile.  I also recently
moved the setup script config files under /etc/schroot/default, so
we could equally provide a /etc/schroot/desktop directory with
the desktop-specific customisations already available.  You would
just need to set script-config=desktop rather than
script-config=default (the default).

Roger
