</I>&gt;&gt;<i> For the record, what does this fix?
</I>&gt;<i>
</I>&gt;<i> Sorry, I should have been more verbose.
</I>&gt;<i>
</I>&gt;<i> Basically because of the previous commit:
</I>&gt;<i> <A HREF="http://svnweb.mageia.org/soft?view=revision&amp;revision=4014">http://svnweb.mageia.org/soft?view=revision&amp;revision=4014</A>
</I>&gt;<i>
</I>&gt;<i> We can now generate a &quot;hostonly&quot; initrd, i.e. a nice small, &quot;normal&quot;
</I>&gt;<i> initrd that we typically produce, tailored for the system in question.
</I>&gt;<i>
</I>&gt;<i> As a fallout from this, when running the install with an encrypted root
</I>&gt;<i> partition (and possibly just a normal LVM, not sure), various udev
</I>&gt;<i> properties were not injected into the udev database. These properties
</I>&gt;<i> (FS_UUID - can be seen via e.g. udevadm info --query=property
</I>&gt;<i> --name=/dev/sda5) as needed by dracut to detect things properly (rather
</I>&gt;<i> than resulting to lots of weird and wonderful probing methods dracut
</I>&gt;<i> tries to use udev as it's primary source of info).
</I>&gt;<i>
</I>&gt;<i> So these rules ensured that the UUID of /dev/sd* partitions were
</I>&gt;<i> available in udev.
</I>
Maybe should we include them into rescue too, shouldn't we?
