Hello,
I have tried to migrating the cron jobs of the inn package to
systemd timers.
Unfortunately, I have got the following problem. After a
install/update of the
package the timer will only start the service unit only once time.
The service
was not started after the configure period was expired. But when I
have restart
the system, it's works as expected.
So I would to ask, what I have to concern when I want to migrate to
systemd timers.
I think that massive migration of services from cron to systemd timers
is very premature and should be actively at least discouraged by
packaging directives.
I'm somewhat skeptical of the benefit of migration in general. I'm really
skeptical that the place you start reducing the dependency load is inn.
I have started looking into migration of cron jobs to native systemd
time units as I mentioned I would do with fesco on the last meeting.
Out of the total 99 cron job the distribution ship there are 38 which
come with service related packages thus might be applicable to migration
from my pov the rest should just be left as is.
What surprised me the most was that none of those components packages
depended on cron which was the same thing with rsyslog when I looked
into that which is what I expected they would do.
Maybe it's just me but is there not something more broken/alarming with
that or is just me and this is just acceptable from packaging standpoint?

It's a problem of incorrect dependencies. Many packagers simply don't
require packages, which are in base group. I found out, when I removed
vixie-cron provides and there were still packages, which had it wrong.
I was forced to remove requirement on rsyslog, because some people
wanted to install system without any logger. I guess I should ask FPC
for a guideline, but as I do not have time for review of all packages,
which incorrectly provide/require package I didn't do it.
What is the added value of migration of cron jobs? I, as maintainer of
cron, obviously don't see the added value. What might be interesting
would be converting cron.daily jobs as systemd task. If systemd could
execute daily job in time, when system load is low, that would be awesome.
