autofs-4.0.0_pre9.ebuild should work. Maybe Daniel can document the naming
pattern
somewhere on the net.

I think that is just a kernel-configuration issue.

2.4.0 does not work correct with reiserfs. Thats why I made packages for
ac2/3/4. (2.4.0.2, 2.4.0.3 ...).
I use 2.4.0.3-r1 at the moment here. 2.4.0.3 includes a buggy nfs-patch, this
patch gets
not applied in 2.4.0.3-r1. In 2.4.0.4 there where a few changes to LFS in the
kernel and
there is only a quick fix for that to work with reiserfs available at the
moment, so
2.4.0.3-r1 is the best choice at the moment but you can't use nfs with
reiserfs.

Sounds interesting, more comments later. :-)
