Thanks for the quick replies!
This solution should work fine, and it's quite simple.
Tomorrow I'll try it.
Thanks for the help. =D

I've aproached this in a slightly differnet manner:
Cron is active on both nodes, crontab is identical on both nodes.
But: contab entries check that a directory on the drbd volume exists, so
the jobs only execute on the primary host.
Example (drbd provides a filesystem that gets mounted as /usr/www)
8 * * * * nobody test -d /usr/www/apache && wget -O /dev/null -q
For my setup that seems to me much easier that fiddling with differnet
crontabs or having multiple cron daemons.
