I see that 3.21 is now released (Dec 22) and that it says it supports
RHEL9. That sounds great. Thank you!
Background to following questions:
- Until about a year ago we were way back at release 3.10 and our policy
was not MPF-compatible at all
- We are now at 3.15 (software) and 3.12 (MPF masterfiles)
- Somewhat over 2000 clients; mostly RH7 and RH8 (a little residual RH6;
starting RH9 development)
I understand 3.15 is now EOL, so we need to start moving up. (We were
going to anyway, but 3.15/EOL encourages that!)
The message above from Vratislav (Nov 3) suggests that RHEL9 ie being
backported to 3.18. Has this been done? (The message references a PR
which appears to have been merged. But has this yet made it to the
community RPMs?) If so that means that I can start my RH9 development at
3.18 rather than needing to start at 3.21, which eases somewhat the version
"stretch" with masterfiles.
Vratislav's message also says that the version of the hub software should
generally be the same as, or ahead of, the clients. Fortunately, I've seen
no bad effects when the reverse is the case (client a little ahead of hub),
but I take the point for general production.
But *within* any machine, what about software version vs. MPF/masterfiles
version? We are currently 3.15 software and 3.12 masterfiles. It seems
OK. Nevertheless I plan to move masterfiles upwards. Can it go ahead of
the software? Indeed, I suspect masterfiles probably should be ahead of
the software. This becomes more important as we cross the 3.18 threshold
(and look further ahead towards 3.21) because a quick test with very new
RPM (3.18 and 3.21) showed issues about "rxdirs", which I suspect will be
eased by having masterfiles significantly later than our current 3.12.
This last point raises another thought. Given that our software version is
3.15 (and likely to stay like that for a few months), can I take the
masterfiles version way up in a giant leap from 3.12 to 3.21? Or am I
better doing masterfiles by a few smaller steps (3.12->3.15->3.18->3.21)?
I would probably do a similar series of steps for the software, although
they may not exactly rise in step with each other.
Advice welcome!
