Just checked the code to remind myself how this is set, and it does
certainly /look/ like it's being set with the alias name rather than
the chroot name.  Possibly it's not being passed the correct name
in chroot_facet_session_clonable::clone_session_setup (which has an
alias argument which is used for the above env vars).

I'll have to investigate that in more detail.  One possible cause
might be if the alias->chroot mappings in sbuild::chroot_config are
not being used correctly, or we pass the wrong value in
sbuild::session.  I'll have to double check that.

One other consideration might be if the chroot is capable of session
cloning, since these are set during setting cloning.  Chroots like
"plain", which are not, might not have this capability--I can't
remember offhand how they are handled, so I'll again have to check.

Roger
