Starting a rocky 9 box (having nfs shares) fails with: `No match for argument: nfs-utils-lib`. Apparently Rocky 9 does not have a `nfs-utils-lib` but mounting nfs shares without nfs-utils-lib works fine. So updating the nfs client install to only install `nfs-utils-lib` if the package is available. That way older rhel clones should continue to work as well.
Vagrant Core Plugins
These are plugins that ship with Vagrant. Vagrant core uses its own plugin system to power a lot of the core pieces that ship with Vagrant. Each plugin will have its own README which explains its specific role.
