No, but if people use features found in bash 2.0, it will not work
with bash 1.x. We need to finish this issue in a separate thread.

Another thread. This is a major part of the LSB specification.
All someone needs to do is write a proposal.

The scripts need to be rely on the standard base or they need to rely
on stuff in /opt/<package>. (In other words, they would need to be
LSB compliant.)

anacron is something else. anacron is software that allows machines
to not be run 24x7 by running cron jobs that were missed after boot.
I'm actually not in favor of requiring a specific solution, but
anacron has been mentioned several times
I do think we need a way for cron jobs to specify whether they should
be run after boot if they have been missed. There may be instances
where jobs don't want to be run after being missed.

I do think there are cases where a wrapper makes more sense, but I
don't actually think this is one of them.
- this is a really flexible system
- /etc/cron.<period> is included in most distributions, the odds that
non-compliant software to use it is high because it is a de-facto
standard
- system administration benefits
- non-distribution specific documentation benefits
