labelling root file system (RELENG_8)

I've tried to re-label an existing (and up to date) 8-STABLE
installation's root partition. This failed, tunefs reports it cannot
write the super block.
I have attempted this sequence:
1. reboot (through BIOS and loader) directly into single-user mode
2. sysctl kern.geom.debugflags=16
3. tunefs -L root /dev/ada0s4a # that's the dev I mount the root
# partition from
Still no joy => tunefs cannot update the super block.
Remounting / as rw doesn't help, as expected.
The root fs uses softupdates but no journalling -- what other hoops do I
need to jump through to create labels for my root ufs file system?
