Except this breaks if you create a similar hard link for
netbsd.old, which I usually do so that at any point if the new
kernel won't work, I can boot netbsd.old and know it's the
second-most-recent kernel (or at least a known-working kernel).
Plus, if you've got netbsd.old set up, you don't even need to
_have_ a /netbsd, and the system will still boot up (if /netbsd
doesn't exist, the bootblocks then check for netbsd.old,
onetbsd, and onetbsd.old). I'm not sure if kvm_mkdb will be
happy without a /netbsd, though....
So to tell kernels apart, I use 'ls -lai /netbsd* | sort -n'.
Then look for the /netbsd, and the one right next to it with
the same inode number is the `extended' name.
