Yes, the problem is also how should this work together with a readonly
rootfs? Our default skeleton has /var/spool as a symlink to /tmp/, so we
cannot add /var/spool/cron/crontabs at build time (unless we change the
skeleton).

What I have done in the past is simply to do it in an init script,
E.G. something like:


# /var/spool is link to /tmp => crontabs are not persistent over boot
mkdir -p /var/spool/cron/crontabs
cp /root/crontab /var/spool/cron/crontabs/root
start-stop-daemon -S -q -p /var/run/crond.pid --exec /usr/sbin/crond -- -l 9

But that isn't very generic.
