==== Rocky Linux(RHEL9) stuff ====

Updates and releases of CentOS Linux® 7 will be discontinued on June 30, 2024. I am currently managing close to 40 servers running CentOS 7 and hosting a variety of applications and services. 

The time has come to migrate them to freshly deployed Rocky 9 servers. I have just started and already encountered some difficulties due to OS and application changes. Time-consuming little problems for which answers are still difficult to find.

Since many CentOS 7/8 and even Rocky8 tutorials and posts out there are now partially obsolete for RHEL9 & Rocky 9 I will be posting updated tutorials or tips if I fail to find already existing and accurate ones.  

==== Ubuntu Linux stuff ====

Unfortunately, RHEL decided to drop support for Btrfs, it makes no sense as Fedora switched to using it as its filesystem by default. Go figure.
I do rely on Btrfs for several incremental backup CentOS 7 servers that I will now have to replace with Ubuntu as it supports it natively. If I come across something Ubuntu-related worth posting, it will go in this section.
 
==== Other stuff ====

Probably a little bit of everything, things I'd like to share or just want to keep handy for myself :-)
