I'm wouldn't mind doing something like this:

nano_confs
while getopts '...' optch
do
    case "$optch" in
    ...
    c)
        nano_confs="$nano_confs $OPTARG"
        ;;
...

for nano_conf in $nano_confs; do
    . $nano_confs
done

The problem I was trying to work around is that (unfortunately) some
packages code features (ipv6) into the names (take apr for instance),
which means that the logic in FreeNAS currently always says "build a
fat image" when $DEBUG == 1.

My concern was that not all of my build machines are homogeneous. I
have access to some "powerhouse" server machines and some low power
desktops. FreeNAS had -j8 coded into NANO_PMAKE, but I made it
variable ($CPUS), but I thought that was a bad idea for what should go
back into nanobsd (it didn't match the defaults and could cause other
issues) -- if the default (1) is incorrect, I'm all for bumping it up
to 3 again. I just wasn't sure why 3 was the chosen default.

Thanks for the feedback!
