I was following the handbook (/usr/share/doc).
There are two methods in 5.1-release of building
a kernel.
Method 1.
The /usr/sbin/config MYKERNEL
cd ../compile/MYKERNEL
make depend
make
make install
Method 2.
cd /usr/src
make buildkernel KERNCONF=MYKERNEL
make installkernel KERNCONF=MYKERNEL
the handbook recommended method 1 if you had not
cvsup. So, I did method 1.
The thing that's throwing me is in 5.1-release, it
brings up a character menu of choices when booting
(complete with ascii art of the mascot). What option
do I choose so I can do:
boot kernel.old ?
thanks,
Darrl
