System: FreeBSD FreeBSD 6.2-STABLE #1: Wed Aug 1 15:06:22 CEST 2007

>Description:

NFS can be tuned very well by using the mount_nfs options mentioned
above. However, currently it is not possible to instruct amd to
use these options when mounting NFS volumes.

>How-To-Repeat:

Try to tell amd to use the options mentioned above.

>Fix:

This patch adds the amd options readahead=X, dumbtimr and nolockd
to amd. It also replaces the patch in PR# 85204 which only adds
the readahead feature.
