With the drbd-utils update to 9.19.0 on Mon Oct 11 09:43:25 UTC 2021 the
/lib/drbd/scripts/drbd directory was moved to /usr (see line#130 in
https://build.opensuse.org/package/view_file/network:ha-clustering:Factory/drbd-utils/drbd-utils.changes?expand=1).
Soon later a fix for bsc#1203220 was introduced because drbd.service now fails
with `drbd.service: Failed at step EXEC spawning /lib/drbd/scripts/drbd: No
such file or directory` and a symlink to /usr was created. Apparently this fix
never made it into Leap15.4 backports:
