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

What I do is make symlinks. This is described in my article on DRBD and
heartbeat here http://www.linux-mag.com/2003-11/availability_01.html (it
talks about an old version of DRBD but the principles are the same).
Sean Reifschneider wrote a tool called DRBDlinks to do something similar
