A colleage of mine here has been jumping through the hoops to get
Slurm 20.11.5 set up, as our user-facing team would like to see it,
on our new Cray Shasta system.

He's said that when, ahead of looking to automate the deployemnt,
he had done a by-hand Zypper install of the slurm-contribs RPM, he
had found that he needed slurm-perlapi as well, because the seff
program, which is what our user-facing team actually want, is a
Perl script.

However, when you interrogate the RPM database, you don't see any
such requirement, just the need for Perl.

nid001028:~ # rpm -qR slurm-contribs
/bin/bash
/usr/bin/perl
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(FileDigests) <= 4.6.0-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rpmlib(PayloadIsXz) <= 5.2-1
slurm(x86-64) = 20.11.5-1
nid001028:~ #
nid001028:~ # rpm -q --whatrequires slurm-perlapi
no package requires slurm-perlapi
nid001028:~ #

and so, if you just install slurm-contribs, you only find out
about the dependency when you come to run seff.

I have verified the same lack of requirement info on a
Slurm 21.08.5 Cray system.

I think it would be "nice" if the requirement info was made
explict in the RPM Specfile.

I note that it is an explict Specfile Requirement for these two sub-packages
