there has been a discussion about if we need cache for man-db for users which use man pages or update system only from time to time and thus don't need to update cache every day. man-db as it is now depends on systemd which brings another set of packages. The use case is "I just want to read man page. So I install man which on the other hand download another set of packages. I want to read man page and it downloads systemd.".
Have you considered installing the timer file, but without the dependency? If systemd is there, it could use it, otherwise not. That would make a whole lot more sense to me than creating another package, and would be my recommendation.
Nope, this is not going to work. If there's no dependency on systemd then during installation rpm can install man-db before systemd and and the timer will not get enabled. Currently it is not possible to install systemd units without a dependency on systemd.
Right which in turn will lead up to the scenario I tried to explain thousand times with FESCO that we would end up having components depend on systemd when they should not and with absolutely no benefit of and worse outcome as well as more frustrating aministrator/enduser experience than continuing to use cron for those jobs as well as obfuscating the work of those working on cleaning up the core/baseOS.
If it would have made sense to migrate every cron job to timer units I would have written and filed a feature proposal then and there which would achieve exactly that but the fact is that systemd timers and cronie are two component that complement each others short comings and systemd has quite few of those shortcomings compared to cron.
Unfortunately people only seem to see the outcome for their own component or their ( cloud ) product instead of thinking about the whole.
If people are so inclined and anxious to drop that cron job then they should spend their time and energy and write that rpm trigger(s) for man in accordance with what Peter Schiffer said as opposed to try to implement this with timer units and or workaround the FPG.
