I know that a filesystem in unix just exists wherever it exists (i.e.
it's 'identity' is its mountpoint), but I find it extremely handy with
ext* and FAT filesystems to be able to give every volume its own name.
I was just living with not being able to do this on OpenBSD, just
discovered dumpfs(8) and noticed a "volname" property snuck in at the
end. It doesn't seem like newfs(8) or tunefs(8) let me set this at
all, but (and you may find this vain) is there any secret tool that
lets me edit these other properties, or an explanation of why they
aren't exposed at least?
