I'm guessing it won't work even if you get it to compile. We've been
trying to get it to work with the F14 latest kernel, and it just won't

to work on the F14 kernel).
The autofs maintainer (Ian Kent) tries to keep the v4 kernel module
compatible with v3. However, if you don't report problems, they won't
get fixed (most testing these days is with autofs version 5).
I reported on both kernel.org and on am-utils.org that autofs and amd do
not work with F12's kernel in March/April of 2010 (kernel.org bug 15878
and am-utils bug 639). No one has acknowledged or worked on the bug, as
far as I can tell on the respective bugzillas.
We have discovered in the last couple of days that the amd compillation
is bad on F14, as is the kernel support for autofs. Copying the amd from
F12 (and the libgdbm library) and installing our custom compiled kernel
from F12 (with autofs enabled) works. amd from 12 with the kernel from
14 (2.6.35.10-74) does not work, nor does amd from 14 with the kernel
from 12 (2.6.32.26-175). amd fails if autofs3 is not on, it does not
recognize autofs4 as being usable.
NB: this is ONLY with amd in autofs mode. amd in nfs mode works, albeit
sluggishly. We cannot use nfs mode because some of our tools don't like
the whole /tmp_mnt structure.
It performs horribly with nfs mode. Think it's time to move onto
supported technology unfortunately (autofs5 is no great shakes, we're
going to try autofs4).
autofs4 isn't exactly supported technology either. You'd be moving from
one dead-end to another. I've CC'd the autofs list. If you have
suggestions and/or specific bugs, please let us know.
A very large installations (40,000+ servers) of linux that I know of
refuses to use autofs5 because of issues with the mutli-threading. I
know no more than that, but I trust their opinion and experience, and
have heard rumblings of other groups having issues with autofs5.
