Please add a comment here explaining what it does and why we chose this
approach.

GUIX_PROFILE is not meant to be systematically defined, but maybe that’s
good enough.

Could you build, say, xterm against this, check whether this fixes the
ctrl-click issue for instance, and also run it in Valgrind to make sure?

If that works, ok for core-updates or the next ‘staging’ since ‘staging’
is now frozen.

Thanks,
