Hmm.
jim@krebstar:~$ which depmod
/usr/local/bin/depmod
jim@krebstar:~$ whereis depmod
depmod: /sbin/depmod /etc/depmod.d /usr/local/bin/depmod
/usr/share/man/man8/depmod.8.gz
So while according to my $PATH preferences I'd rather run
/usr/local/bin/depmod, it looks like the '{print $2}' thing would pick
/sbin/depmod instead.
Not a big deal, but I suspect those sort of considerations are why the
scripts tend just to check the $PATH.
