I guess it's wrong information... Where is the name of the current
kernel supposed to be gotten from ? None of the documentation seems
to point anywhere else.
Personally, I think my change was wrong. The installkernel code should
check to see if kern.bootfile is already kernel.old, and if it is,
shouldn't move /boot/kernel/ on top of it.
WRT sysctl(8) not being in the path, are you suggesting that I spell
it /sbin/sysctl ? And WRT the command failing, are you suggesting
that I simply put a ``-'' in front of the command ?
