If you find you need to roll back, you can do things like dnf downgrade ...

 

NB:  perfSONAR is not guaranteed to work across a downgrade because the database that underpins pScheduler can only be re-versioned forward.  The only way we could make downgrades work reliably would be to maintain code to make them happen (a lot of work for relatively-little benefit) or detect them and destroy/rebuild the database (astonishing behavior).  Generally, our policy is to make production releases stable-enough that downgrades aren’t necessary and get bug fixes get out quickly-enough that the right path is an upgrade.

 

   I'm not saying there is anything wrong with the strategy of a new folder for each release and changing the pointer, but its not what a lot of EL admins would expect based on how minor versions of packages are released for a lot of other EL repos.

 

There’s nothing stopping us from producing a set of repo data with everything and still maintaining the existing directory structure.  That would also enable “dnf reinstall” on systems running older versions.  That said, we really, really recommend installing the current version.

 

I’ve opened an issue on considering that:  https://github.com/perfsonar/project/issues/1356.
