How to add an RPM so it is available to a CloudLinux cagefs user.

Question

How do I add an RPM so it is available to users caged via cagefs?

Answer

There is a cagefsctl command that can be used to add the RPM and then sync the add so it is available to users.

Example adding the ftp RPM so the ftp client is available.

cagefsctl --addrpm ftp
cagefsctl --force-update
