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

You're welcome, any constructive criticism is appreciated, I plan to
write many more. so if we can get any of the minor things out of the way
lets do it early on! :)

This I don't know, I actually used Florian's fine work to assist in
writing it.

Huh, I swear I saw it there before. I guess it's not.

"Up" brings the device up "drbdadm up resource" is an alias for:

"adjust" makes changes to the running drbd.conf without having to
restart DRBD.
