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

I can imagine there is, but it's going to be ugly and dangerous.

Technically, if you'd manipulate the local metadata to make your UUID
36357CED276F2436, DRBD would assume that it can perform a quicksync (I
believe).

Again: This is obviously far from clean or safe (and I don't know where
one could find info on how to do it).

Personally, I'd rather mail a hard disk and do
