/etc/init.d/autofs is started before and stopped after netfs. Therefore, if /usr is on a NFS server, start will fail (/usr/sbin/automount ...). netfs shutdown will also fail (automount still running) before killing automount.
This defect is considered MUST-FIX for Florence Gold release
The priorities for autofs will match am-utils (start 28, stop 72) in autofs-3.1.7-3 and later.
