Support #21855
Updated by Peter Amstutz about 1 month ago
Because CentOS has mutated from being a stable RHEL-compatible distro to a rolling distro that is no longer a suitable development target, we will stop supporting it in Arvados 3.0. That makes it weird to have the repository path https://rpm.arvados.org/CentOS
This should be renamed https://rpm.arvados.org/RHEL and the relevant package build scripts and documentation updated to use that. (I spent an inordinate amount of time trying to figure out if there was a naming scheme we should be following but came up empty, so RHEL is the most straightforward name to use here.)
For backwards compatibility, https://rpm.arvados.org/CentOS should continue to exist and serve already-released packages. For simplicity we could link CentOS and RHEL to the same directory, but that will eventually lead to weird things like packages showing up in a "/CentOS/9" directory when CentOS 9 doesn't exist.
Also, should we be distributing against point releases? E.g. perhaps our packages should be "/RHEL/8.6" because we are using python 3.9 packages that were not in the 8.0 release but became available in a point release later. (I don't know what the best practice is here, it seems that the client is configured with just the /RHEL/ path and selects the appropriate version on its own).
For example, https://download.rockylinux.org/pub/rocky/ has individual point releases, although it may be that the major version simply tracks the most recent minor version.
