Hi, the /tmp in a shell container is not read only which seems to break a lot of things. For example when I try to build Guix from source:
--8<---------------cut here---------------start------------->8--- $ guix time-machine -q --commit=4a32b83753b124169003589fae42eff03ff482cc -- shell -CD guix -- ./bootstrap [..] + autoreconf -vfi autoreconf: cannot create /tmp/ar9117.8: Read-only file system --8<---------------cut here---------------end--------------->8--- Passing the new --writable-root works around the problem.
