Nit-pick: Instead of reusing the commit title here, it would be better
to mention what is being done, e.g. "Use SESSREG to register X11
session".

I'm surprised that this works.  I would have expected sessreg to be
unbound in this context, and that it would have to be added to the
<slim-configuration> record similar to xauth and startx.

However I suspect it may be better to add it to the record regardless,
to stay consistent and allow overriding it.  WDYT?

This is a change that affects most GuixSD users, so we better not break
anything here :-)
