No sub-forum for Oracle Linux? that's will be my next install.

It's just Red Hat tuned for Oracle's databases. Personally I wouldn't waste my time but maybe it will work for you. My last job had hundreds of Oracle Linux boxes and we ended up moving them back to Red Hat because of technical reasons.

What about renaming the "Red Hat" forum to something like "Red Hat / RHEL / derivatives", with the description mentioning Oracle, Rocky, Springdale, etc?

It will be my 1st post at this forum but I think it is absolutely good idea.

Really? What version of OEL are you using now?

I guess that does not count at all. I mean I would use this forum for any problems related to any derivatives, that looks obvious for me (without changing the title).

Oracle EL 7 u2 64-bit since 2016.

Just installed and tested Oracle Linux 8.5 (AArch64) on the Raspberry Pi 4. First thing I noticed is that at boot time the PWR and ACT LEDs are turned off on purpose, after initially starting up as normal. Who in their right mind thinks that disabling the status LEDs is a good idea?

I eventually found out the system had in fact booted and I was able to log in - even though I'd assumed there was a kernel panic and the boot loader had died. So I updated the system and installed a few packages; tmux, nano, and a few others. I checked the date, fstab, partitions, and resized the root partition to use the full capacity of the storage device. Then, when thinking about what to play around with, I decided it might be interesting to set up a NTP server. Interesting? Hell no! Torture is more accurate - which has the potential to leave you with suicidal tendencies and cause you to self-harm. NTP is now a thing of the past and Chrony is its replacement, apparently. After reading a little into Chrony and seeing how it works I found that it's no better or worse than NTP but it is much more convoluted and time consuming to configure and get working - and poorly documented on the Internet.

Then I thought the man pages might offer some greater insight than Google. Oh boy was I WRONG! There's no man pages to be found on the system - I had to install the package first! WTF?!?!

Conclusion: Oracle Linux is less enlightening than banging your head against a wall to see if it hurts.

So, perhaps be thankful there is no Oracle Linux sub-forum.
