I tend to favor unique solutions for unique problems, and general
solutions only for general problems, so I'd think twice about that.

Take two. I skimmed over the part about the package not even
extracting without compat_12, so maybe a test is called for. You can
use "nm" to test for symbols in the kernel, as follows. It doesn't
work right if the kernel you booted from isn't named "netbsd", but
then a lot of other things don't work, either. Ideally, you would test
for the exact syscalls that the binary needs, with due consideration
to the fact that it may be different on a.out and ELF--compat_12_lstat
or aout_compat_12_lstat, for example--but this illustrates the idea.
