Why wazuh-manager service won't start on boot and cant be enabled. (on alma/rocky rhel compatible linux)

[TheBigBear]

Here is the solution once it has happened.

Why wazuh-manager service wont start on boot and can't be enabled.

The same happens on almalinux 9.2 (probably on most RHEL/CENTOS compatible OSes actually - as they are all systemd systems)

It would be so much nicer if we were told to 1st install chckconfig. As it can not be installed later once wazuh-manager with the first SysV scripts has been installed, without manual fixup and intervention.

I am including the actual output and errors that show when one tries to enable it in the hope that others having the issue will find this solution.
