Could the hurd buildd people possibly take a look here?

Sure, but what I mean here is this: can you recreate the mounts which
schroot sets up without involving schroot.  schroot itself just
mounts some filesystems and executes a chrooted program/shell; it's
not doing any magic.  If "mv" is failing then there's a fault in
the system itself, though the way schroot set up the mounts may
trigger it.

CCing the hurd porters.  I would certainly appreciate some help
investigating the above issue, and getting some hurd-specific
templates into schroot will hopefully result in a decent default
setup for hurd schroot/sbuild/buildd users.
