In fstab(5)[1] I found something like:
To use ``NAME'' on a non-GPT disk, use:
NAME=sb2k5Root/a / ffs rw,log 1 1
NAME=sb2k5Root/b none swap sw,dp 0 0
For a gpt(8) disk, use:
NAME=firstpartition / ffs rw,log 1 1
NAME=secondpartition none swap sw,dp 0 0
- NAMEs in non-gpt mode are created from device name, I presume.
Maybe something like this will be better:
NAME=@root/a / ffs rw,log 1 1
or even:
NAME=@kern.root_device/a
'@' may be used to keep consistent "magic" format with other cases
(ie. symlink(7)[2]).
