It being /etc/crontab I don't think that it's necessarily risky.  Usually
the files in the cron spool directory is where I think there might be more
risk involved in causing corruption.  However, /etc/crontab would seem to
be linux specific.  I don't have an /etc/crontab on the solaris hosts I
manage, so I don't think it's completely portable to do it using that
method.

If I can use /etc/crontab on solaris, I'd be more than willing to give it 
a shot.
