Subject: [PATCH] [zfs] adding hostid using ZFS in combination with dracut
 exposed a bug on system updates hostid from the Live session does not match
 hostid installed, thus zpool id no longer matches id created by dracut in the
 kernel img to work around this, the zfs module now uses zgenhostid to create
 a hostid
