Though it's not a transition package of course...

It's maintained by a team instead of by an individual and as you
mention: the team is trying to reduce that risk, so I don't see a reason
to keep a seperate dchroot source package as there is no upstream.

All the reported bugs in schroot are tagged pending, though bug #354344
(schroot: please use mount --rbind when mounting session-managed plain
chroots) is blocked by another bug, did lamont promiss a fix or are you
using /proc/mounts? I didn't have a look at the svn repository yet,
though I'll probably do that in the near future...

Looks good :-)

So, I'd better file the removal bug for the dchroot source package?! :-)
