Linux `alternatives --config` without user input

Question

I am writing a RHEL kickstart script, and in my %post, I need to install a JRE.

Basically, the current setup involves me needing to manually go in after first boot and set the newly installed JRE as the default using the alternatives --config command. Is there a way for me to pass arguments to alternatives so I don't have to manually pick the correct JRE?

Answer 1

Does your version have --set?

--set name path
Set the program path as alternative for name. This is equivalent to --config but is non-interactive and thus scriptable.
