Hi again,
Well, I don't know what is this /var/lib/drbd directory, but here is a
patch in order to take in account the "make PREFIX=" command
Tell me if it is OK for you.
And so, last question, what is the aim of this directory ? I have seen
drbdadm create symbolic link to the configuration file, but why ?
