Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

In general it is a good idea to remove old, maybe outdated/leftover
*.res files on startup. We had some issues with conflicting minor
numbers and what not.

We removed them on startup, but only generated them later. With
drbdmange 0.97.1 all res files get removed on startup, and the ones from
known resources get created on startup immediately. This should help for
example the manual "drbdadm" case.

BTW: you don't have to set/uset resource options to trigger an export of
res files:
drbdmanage export-res "*" # the quotes are important
