It seems to me that either the isaconf and the modload order is inverted, or that the kernel should be demand loading the driver for the isaconf case if the driver were not already present (the loading done by the *kernel*, not the *isaconf*)... in which case there should not be a modload at all. > That is I'd like to be able to boot a generic thing, and have it > preserve my deltas to the "settings" of the device drivers across > upgrades.

That way I can upgrade my /etc/rc* without the machine not working... Heh.
