Philipp,

Thanks so much for all your efforts with this terrific application!

I have a request for your next release. In drbd.conf you require the 
addresses of each of the nodes to be actual physical IP addresses. In 
drbd-6, I was able to use hostnames (which were ultimately defined in 
/etc/hosts), but I cannot seem to do that anymore with drbd-7. Now if I 
need to change the IP address of one of the nodes, I must edit 4 files. I 
must edit both /etc/hosts and /etc/drbd.conf on both nodes and I must edit 
multiple instances of the IP address in drbd.conf  (one for each resource). 
Previously, I just changed /etc/hosts on both nodes, restarted, and I was done.

Thanks for your consideration,

Ward
