That would be great, thanks.

Fantastic. Judging by the other bug, it looks like they bodged around
the problem with effective/real UIDs in the other suid-root package.
I'd rather not do that, and wait for a correct fix.

Yes. However, note that LVM device locking won't work without 1.0.2
at the very least, because older versions don't support devices in
subdirectories of /dev. I added support to lockdev so that we could
do just this:
2005-10-03 Roger Leigh <rleigh at debian.org>
* Version 1.0.2.
(General) Replace the use of __linux__ with __GNU_LIBRARY__, and
use the GNU libc gnu_dev_major() and gnu_dev_minor() functions
rather than kernel macros.
(General) Convert K&R C into ISO C89 C.
(_dl_filename_1): Remove special casing for CUA devices on Linux
systems; these devices have long been deprecated and are no longer
available in current kernels.
(_dl_filename_2): If a device name has '/' separators in its name,
replace them with ':'s. This is to support devices in
(_dl_check_devname): If a device pathname starts with DEV_PATH,
e.g. "/dev/", strip off only "/dev/", rather than the entire path.
This is to support devices in subdirectories under /dev,
e.g. DevFS, udev, devpts and LVM.

The problem with this is that it might also be in /usr/local, or
somewhere else. We should really check with configure, and otherwise
fall back to /sbin as a sensible default. Adding to the build-deps is
not a big deal--if not installed it will use the fallback, and it will
also check with "test -x" at runtime.

This is now done, so you can if you wish clone a copy of the
repository from git://git.debian.org/git/buildd-tools/schroot.git
Try "git clone git://git.debian.org/git/buildd-tools/schroot.git
schroot" as a starting point.
