Any idea how this could have happened after disabling everything in
my /etc/loader.conf, and simply running a:
make buildworld
make buildkernel KERNCONF=myconfig
make installkernel KERNCONF=myconfig
Shouldn't this have installed a fresh kernel plus only essential
modules?
Here is a diff of my kernel config (which I've called, rather
uncreatively, 6.x) against GENERIC:
nothing unusual, just IPFIREWALL and Linux compat stuff, right?
