disable_prelink

=head1 USAGE

scripts/disable_prelink [--help]

=head1 DESCRIPTION

This script disables RPM prelinking. It is run nightly so we are sure it does not re-appear.

If you want to disable this behavior, you can touch /var/cpanel/dont_remove_prelink.

B<WARNING>: Prelinking often causes issues, and we no longer support it as of cPanel & WHM version 54.
When you enable prelinking, you may experience problems with broken RPMs.

See https://go.cpanel.net/how-to-disable-prelinking for further information
