Re: rc script to let a service wait for db available

This isn't entirely true. rc scripts have a default PATH and HOME. From service(8):

ENVIRONMENT
     When used to run rc.d scripts the service command sets HOME to / and PATH
     to /sbin:/bin:/usr/sbin:/usr/bin which is how they are set in /etc/rc at
     boot time.

Something similar holds true for `cron' as well. I see a lot of unnecessary setting of
absolute paths for binaries that reside in default PATHs.
