} Interesting, especially as there's an options MODULAR in netbsd-5's

You'll note that there is also options LKM and that all
filesystems are included in GENERIC. netbsd-5 is basically a
transition from LKM to kmod and has some support for both.

It may be possible that if you remove filesystems from your
kernel, that they would get autoloaded. I don't recall if filesystem
autoloading is in netbsd-5 or not.

kmods are a major improvement on LKMs. kmods as they sit, work.
The issue seems to be around usability. There also seems to be some
contention around a design point. kmods were designed to work with all
kernels of a particular version. Some people want them to be
associated with a particular kernel instead. This is more of a
subjective preference then a design issue. Either way can work and
function just fine for many purposes.
