Thanks for responding, Gavin,

That's seems a bit drastic.  I have already customized my chroot a
bit, plus it seems like one should be able to upgrade the chroot as a
part of normal maintenance for bug fixes and security updates.

I assume ltsp-build-client, besides downloading all the recent
packages, then runs ltsp-update-sshkeys, ltsp-update-kernels, and
ltsp-update-image?  Would that therefore also create

Then I'd need to build a new nbd image to go with that, no?
