No. I am seeing different behavior. Looks like 'autofs' behavior.
I can't _really_ tell which driver is being used. As a module I can
'lsmod'. But how do you tell if it is not a module? But the behavior
is matching 'autofs' behavior so I am assuming that is the one being
used and not 'autofs4'.
I believe autofs4 is also needed for NFSpv3 support. Otherwise you
just get NFSpv2. But don't quote me on that. In any case, I think
autofs4 should be the default. It is not in the 686 kernel either but
both are modules so it can be selected easily enough.

I assume that means either as a module or as compiled into the kernel.
I think they really just mean selected for your kernel. It needs
wordsmithing. (BTW, I don't see that documentation with the current
version of autofs in stable.)

I can't think of any reason. Obviously I would prefer it as a module
because then I would not be having this issue.
Just to be clear, this is Bdale's kernel-image-2.4.19-mckinley-smp
from debian.org and it is compiled it in, not a module, for the stock
Debian kernel. So I can't answer why it is that way. I would guess
that it has not been made visible as an issue until now.
