+
+In certain circumstances, yes. If you have dm or raid or anything
+similar, mkinitrd simply won't work as systemd aims to be very much
+focused on hotplug, not on probing and poking as traditional systems
+used to work. This means that metadata about disks and drives must be
+available via udev. In the old mkinitrd approach, udev is not used and
+thus when lvm and friends are activated inside the initrd, the metadata
+does not make it through to udev and thus systemd cannot "see" various
+partitions and thus cannot mount filesystems etc.
+
+Using dracut means udev is in the initrd and metadata is available.
+
+This is why a systemd boot requires a dracut initrd. I'm not prepared to
+support any other combination as it just does not make sense.
+
+Can I ask why you are using mkinitrd anyway? What problem are you having
+with dracut? I need to make sure I find a way to fix any problems you
+have (obviously some problems with latest dracut are known and I'm
+working on fixes, just want to make sure I don't miss your issues)
