No worries. And I hope you get better soon!

Well, technically if somebody mounts it read-only before and does not
umount it before calling adt-reboot, it may also cause problems, but I
figure the current wording in the man page is enough - because people
really _shouldn't_ do this, because any QEMU instance using the
baseimage should have already been terminated at that point, and I
think we can presume that people using this feature will at least have
some degree of competency.

Ok, phew! :)

Yes. :)

I just build-tested the current git master in a clean pbuilder chroot.
No lintian messages except the override with:
lintian -L '>=pedantic/wild-guess'

I've also tried to use adt-run on my preliminary open-iscsi tests, and
no problems there.

So from my perspective, it's all set. :-)

Regards,
Christian

PS: Once you're feeling better, it would be great if you could comment
on my open-iscsi tests (see other thread I CC'd to autopkgtest-devel).
