I don't really have a "real" solution to this problem. It seems hwclock is really, really messed up. That said, maybe I'm missing the point. I'll explain the way I see it, and you tell me if i got it all wrong.
Turns out I missed the point, and that things are actually fine they way they are upstream. We should slightly change our initscripts though, and move adjfile to /etc. The point being, that we never need to write to adjfile on boot, but we can read it, it will only be written to on shutdown. Furthermore, --systohc/--set will only be called manually by the sysadmin when s/he knows that it makes sense to calibrate the time and drift. --systohc, if you know that your system has been running since the last --set/--systohc this can be used to calculate the drift-rate. --set, this is (obviously) used to set the real time, and to calculate the drift-rate since the last --set/--systohc. -t
