Provide packages for all Slurm versions

[pshunter]

Hi,
unless I missed it, it seems that provided packages (through e.g. galaxy repo) only match Slurm versions found in official distribution releases.
Unfortunately, the calendar for distributions releases and Slurm releases does not match and some Slurm versions get skipped.
Slurm can be upgraded without being shut down provided that only one release maximum is skipped. E.g. clients 20.11, 21.08 and of course 22.05 can work with a 22.05 controller. Sometimes more than one Slurm release is skipped between official distributions. This is a minor problem for Debian because Sid always gets updated quickly and everything can be found in snapshot.debian.org. These packages also usually work on Ubuntu.

In the end I'm always able to find packages to do a seamless upgrade. Last bit missing are drmaa packages matching Slurm releases (libslurmXX). For now I need to rebuild it should the case arise that my target release is not part of an official distribution.

Thank you,
J.C.H

This is tricky for Debian and Ubuntu since I don't build packages for Slurm for these platforms at all, I just use the upstream packages. I could grab the sid packages periodically and build for them, I suppose, but my Debian architecture is already a mess, so that will probably take some time. Are you running the intermediate versions for any length of time, or do you just go from e.g. Slurm 21.08 on Ubuntu 22.04, briefly install each intermediate Slurm version from the sid packages just to get the state files updated, and then settle on Slurm 23.11 in 24.04? You shouldn't need to install intermediate slurm-drmaa packages if you're just doing the upgrade process.

For anyone else who comes along, I do have slurm-drmaa built for all the Slurm versions for EL7 and EL8 under https://depot.galaxyproject.org/yum/package/slurm/. I don't have my build system working with EL9 just yet, hopefully that should be done before too much longer.
