Subject: [PATCH] fips: ensure fs module for /boot is installed
|
|
|
e83cdd |
|
|
|
e83cdd |
When using dracut with --hostonly and --no-hostonly-default-device,
|
|
|
e83cdd |
/boot will be inaccessible as dracut will most fs modules unless
|
|
|
e83cdd |
specified. But FIPS require /boot to be accessible, and it will try
|
|
|
e83cdd |
to mount it on boot. It will fail if corresponding fs module is missing.
|
|
|
e83cdd |
|
|
|
e83cdd |
For most case /boot will be a simple partition, include the fs module
|
|
|
e83cdd |
will be enough for FIPS to mount it. For other cases users have to pass
|
|
|
e83cdd |
extra parameters by themselves.
