It would seem that CONFIG_UID16=y is the culprit after all, no?

Is there a way we can detect kernel misconfiguration and that does not
involve /proc/config.gz?

If not, perhaps we could do precisely the test above in one of the early
derivations in commencement.scm: run “sh -c 'test -w /'” and fail right
away if that doesn’t work.

WDYT?

Ludo’.
