Ok this sounds familar to me - maybe I have read about this before ;)
What would be the prefered way to label the root partition and changing
fstab without entering the root partition at bootup manually at least
once? Is there a way to do so?

I noticed that even when I boot in multiuser, change fstab, then return
into single user mode and remount / read-only, the label cannot be set.
I need to boot directly into single user mode. Looks like writing the
label is denied when the partition was once mounted rw before - even if
it is actually mounted ro.
