Nope, but I know the pain of trying to hack around the problem when
writing the ZFS Automatic Snapshots SMF service - each instance of that,
when enabled adds an entry to the root crontab, and removes it when it's
disabled.
On service startup, I needed to serialise around my updating the
crontab, otherwise the crontab updates setup on each other. Having a
solution to that would be great too.
I echo the other comments in this thread about the time formats - trying
to say "do this every 5 days" in cron at the moment is really tricky to
do properly (see my comments in the start method code below [1])

As with Nico, I'd be more than happy to help test!
