Hmmm.  I'm not sure.  It solves a particular class of problems, yes.

When you have a "crowded" / (netbsd.old, netbsd. netbsd.GENERIC,
netbsd.gz, etc) and you have no "booted_kernel", how do you know
which one you are using?  Which one can I delete?  "uname -a"
and searching with strings is fine so long as you don't have one
with securelevel=-1 and another with securelevel=0 from the same
kernel build.  I think it was this that made me ask this question.
