OK.  (Though GuixSD containers do have /etc/profile, don’t they?)

OK.

I think it would make sense to add a test to (gnu tests ssh) for this,
because it’s one of these things that annoy everyone.

If sshd performs tilde expansion, that’s fine with me.

Should we do something similar for lsh and Dropbear?
