How can I ensure certain kernel modules are included in the initrd or initramfs in RHEL?

Solution Verified - Updated -

Issue

  • How can I configure the system to load a module early in the boot process?
  • How can I ensure mkinitrd includes certain modules in RHEL 4 and 5?
  • How can I ensure dracut includes certain modules in RHEL 6?
  • When I manually run mkinitrd I can include my own modules using --with=<module>, but I need to configure the system so that modules will be included when mkinitrd is run automatically by a kernel rpm installation.
