Fwiw, what we are doing for a customer is to put the config in some
directory on the data partition, and point a symlink there from
/etc/postgresql/$version. That way, the config is also invisible while
the filesystem is on the other node and hence I've never seen this
problem.

PgCommon.pm is now ignoring all errors from df. As pg_checksystem is
just meant as a sanity check, that sounded like the best option for
me.
