We currently include the following packages in the default server install:
* lm_sensors * openhpi * smp_utils
Of these packages, lm_sensors pulls in 33MB of dependencies (mostly PERL, including the PERL interpreter). I'm not personally sure if there's sufficient value in lm_sensors to justify installing it by default. (Pulling in an entire language interpreter just to support this one package seems like overkill).
openhpi and smp_utils are far more self-contained. openhpi pulls in net-snmp-libs and libsysfs, while smp_utils doesn't have any additional deps that aren't already part of the basic system.
That said, I'd like to know what people think about moving the @server-hardware-support group out of the mandatory install set and into the optional install set. All together, we're looking at about 43MB of on-disk usage for these three packages and their dependencies (above the packages in the minimal install).

It the dep on Perl still only for the two interactive (!) scripts in the lm_sensors package?
Or has anything changed that would strictly require those two scripts to be available by default?
One script converts from ancient config file format to the current format. => Not needed since many years.
The other script may be essential, because without running it, you likely don't have any working config file to begin with. It tries to detect h/w but still isn't automatic. There's still a big fat warning about running it with --auto option.
Are other tools in the lm_sensors base package really useful without a config file?

This also means it's not necessary after initial configuration and could be uninstalled. Looks like a candidate for non-mandatory subpackage to me.

Looks like the dep is there to satisfy /usr/bin/sensors-conf-convert and /usr/sbin/sensors-detect

Yeah, look like /usr/bin/sensors-conf-convert could be dropped entirely (or at least moved into a non-required subpackage).

Looks like it really isn't useful without manual configuration (we don't run `sensors-detect --auto` at any point). That to me says that we should remove this package from the default installation and also revoke its status in the systemd presets, since it doesn't meet the criteria specified in https://fedoraproject.org/wiki/Packaging:DefaultServices#Locally_running_ser...
OK, with this in mind, I'm removing lm_sensors from the default package set.

I would drop openhpi from the general purpose server groups completely. I've learned that it is used mainly in telco deployments, which is a very specific use case.
