>Description:

/a is the mountpoint for autofs like:

map /etc/auto_arnold on /a type autofs

% ls -ld /a
ls: /a: Operation not supported
drwxr-xr-x  3 root  wheel  512 Dec 10 16:45 /a

This is a failing lpathconf() call that isn't implemented for autofs.

>How-To-Repeat:
Try to list a autofs mountpoint.
>Fix:
Either filter this error message in ls or teach autofs a VOP_PATHCONF method.
