tunefs(8) changes don't stick

I have a UFS file system on a GPT formatted SSD. I assume that trim is a
desirable flag, but, even though I have tried to set it and it appears set
after the 'tunefs -t', after my next boot it reverts to disabled.
Similarly, changing the volume name (tunefs -L name) also reverts to its
old value.

Any idea what could cause this? Should I consider the -A option? The
warning on that is quite strong, but for those changes, I don't see an
issue with it.
