If you use 'crontabs', they run like the old cron. Only things

Yes, that's the point I and others are trying to make.
It's all those "only" things that are so involved with system
administration & maintenance that are there 'out of the box'.
Of course us 'experts' ...
but the OP was the guy that got hit THUD! by these "only" things
rendering his system unusable and asking us for help.

But but but... you said:

You can't, as John asks, determine the time each specific one runs at.
^^^^---- ???
You can only set the time that cron.{daily,weekly,monthly} runs at, and
that to 15 minute granularity.

You can't, as is possible with ...the real cron ...
run something "only on Monday" or "not on weekends" or "on the
last Friday of the month".

You asserted that the exact scheduling wasn't available with the current cron
that supports the anacron (batch) scheduling feature, but cronie supports
both and AFAIK, it's the latest version of a cron to ship on openSuse systems

Do not assume that everyone else has our knowledge and experience; do
not assume everyone has had the time to dig into how the system works.
I didn't assume -- I just looked at the manpage and saw it supported
both. You asserted that the current cron didn't have this capability.
I am seeing your statements as internally inconsistent.

There are may people here who don't have our knowledge and experience
nor the ability to both contradict one's self in the same
discussion, yet not recognize it.

and that's why they ask here for our help and guidance.

Sorry, but I find the information you provided a bit
confusing. I'm sure it was clear to you, but I'm just saying...
(obligatory disclaimer: some people claim my descriptions are,
at times, confusing, so I am not speaking from 'sainthood' ;-))
