> I have installed StumpWM and some contrib modules, on a Fedora 33 distribution using the guix PM, for many month, without much problem. Since the begining of the week (last guix update), whenever I load a contrib module, StumpWM complains about a FASL file being read-only somewhere in /gnu/store/<hash>-stumpwm-lib.

This is strange, as the last change directly related to StumpWM was
made several months ago (around 2020-12-10).

How do you start StumpWM? Do you use a '.xsession' file?
What are your XDG_CONFIG_DIRS and XDG_DATA_DIRS environment variables
set to?
