In my experience the filesystem options menu doesn't work at all, i.e.
the options select there are just ignored also when selecting them just
once and not re-entering that menu. I've tried to create a filesystem
with SUJ disabled and TRIM enabled twice now, last time with BETA2 on
amd64, and I always end up with a filesystem that has SUJ enabled but
TRIM disabled.
