I did a kernel autofs on 4-Stable a while back, up to the prototype stage.
I did not get to add FreeBSD autofs support to amd, which would have been
my next stage. Note that amd 6.1 supports autofs. Being compatible with the
userland syntax of the Sun automounter is another matter.
My autofs used nullfs, so that has to be reliable.
