since the module is loaded if neccessary from /etc/init.d/drbd,
and I need to know the module parameter minor_count, yes, I need
to parse the conf file first.

maybe better place a test -e /proc/drbd in the remove script.
or diff the drbd.conf against the example copy in the documentation.

but you are right, stopping it when unused should not fail.

maybe this is more appropriate:

diff -u -p -r1.56 drbd
