[Ace] caRepeater on RHEL 9

[Anthony Cuffe]

In the past, we have relied on caRepeater always being in the path of the first person to do something epics related.  On some systems we deliberately starting it from an init script.  For RHEL 9, I wanted to solve this problem more globally.  I created an RPM for just caRepeater that installs in in /usr/bin and creates a system startup script for it (similar to the old /etc/init.d scripts).  The system daemon will watch the process and restart it if it dies.

Does anyone have any issues with this occurring on all systems by default?  We could remove the rpm on systems where this might cause some sort of problem.

This is only for RHEL 9 unless it works so well everyone wants me to back-port it.

Here is the RPM information.
