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.

Tomas
