This is good ... although making a backup of GENERIC is

This is the _old_ way. I believe it still works, but I
don't know if it's supported any longer, and besides, it's
just more work than needed. The docs describe the newer
method, which is
make buildkernel KERNCONF=MYKERNEL
<reboot to single-user mode>
make installkernel KERNCONF=MYKERNEL

This is a completely different thing than compiling a kernel.
If you want the linuxulator installed, definately do this,
but it's not really related to building a kernel.
You don't mention if you've updated your source code or not.
Just a warning, if you _did_ update your source code, you need
to remake world as well as the kernel or you'll have trouble.
If you didn't update your source, the steps outlined above
should cover everything.
