The attached patch changes the behaviour of geom_vol_ffs so that:
- It works even if the file system doesn't fill the partition
completely (it only checks for file system > mediasize).
- It does not attach to providers it doesn't know how to handle.
- It does not attach to sunlabel providers

(I know it wouldn't work for FFS filesystems in non-BSD partitions,
which must be supported. It was not my suggest

Given that it should be OK to have a file system smaller than the
partition

I've nailed it down to this: geom_vol_ffs assumes that a file system
is able to fill the partition completely. That's not a valid
assumption, since the file system size is a multiple of the file
system block size (in my case 16k bytes = 32 blocks), and the
partition size is/should be a multiple of
I have problems getting geom_vol_ffs to recognise one of my file
systems. I set sysctl kern.geom.debugflags=1, and then label ad0s3a
and ad0s3e:
# cd /dev/vol
# ls -l
# tunefs -L 'curroot' /dev/ad0s3a
# ls -l
