Sorry, to reply to myself, but as always talking about my problems
makes it all clearer:

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.
