You misunderstand. I have a fairly minimal kernel.ko. You have to
compile "/ device" into your kernel means that you have to compile the
device that you get your "/" partition from.
Sorry if that didn't parse.
Right now I have kinda gross things like the following in my devd.conf
file:
nomatch 10 {
match "bus" "cardbus[0-9]+";
match "vendor" "0x10b7";
match "device" "0x5257";
action "kldload if_xl";
};
nomatch 10 {
match "bus" "pccard[0-9]+";
match "manufacturer" "0x015f";
match "product" "0x000a";
action "kldload if_an";
};
I've just gotten this working with devd, so I've not had a chance to
optimize things completely at this point in time. However, the above
entries have allowed me to compile a minimal kernel.ko and have the
devices loaded on demand. I don't bother trying to unload them on
last use, however, since that is a big pita...
