kernel modules installed in wrong place?

[walt <wa1ter@xxxxxxxxxxxxx>]

I just pulled from the git mirror at theshell.com and built world,
and also kernel -- but using the old-style method of running 'config'
from /usr/src/sys/config and then compiling in the sys/compile directory.

The building went fine, but the 'install' target put the kernel modules
in / instead of /boot/modules. (The old modules did, however, go in the
/boot/modules.old directory.)

Is the old method still supported, BTW?  It's been working well for me
until today's update.
