Subject: [PATCH] cpu-partitioning: autodetect dracut hook directory,
|
||||
workaround for systemd

MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

|
||||
Wrong hook directory can make the machine unbootable:
|
||||
https://issues.redhat.com/browse/RHEL-119889
|
||||
|
||||
Also added workaround for currently non-functional systemd plugin
|
||||
which doesn't include the systemd config into the initrd image.
