Subject: [PATCH] fips: ensure fs module for /boot is installed
When using dracut with --hostonly and --no-hostonly-default-device,
/boot will be inaccessible as dracut will most fs modules unless
specified. But FIPS require /boot to be accessible, and it will try
to mount it on boot. It will fail if corresponding fs module is missing.
For most case /boot will be a simple partition, include the fs module
will be enough for FIPS to mount it. For other cases users have to pass
extra parameters by themselves.
