Re: Problems with NetworkManager and autofs/NFS

NetworkManager is currently (in devel and F7) unusable with autofs and
NFS mounts.  This is because NetworkManager is stopped very early in the
shutdown process (K02) and brings down the network with it.  Then when
autofs attempts to unmount any automounted nfs mounts, they fail because
the remote machine is not accessible.  Eventually the machine hangs
trying to unmount the last nfs mounted directory.  I suppose it might
timeout eventually, but it's beyond my patience to wait that long.

Questions:

- Why is NetworkManager shutdown so early?

- Should autofs/nfs shutdown do a forced unmount if needed?  Would that
work?

- Do we need tighter NIS/autofs integration into NetworkManager?

Moving forward  we need much tighter integration with all NetworkManager and all
network services on the machine.  What I have done to reduce contention as well
as boot time is to remove the following services from my init process

iscsi
iscsid
ntpd
autofs
sshd
avahi-daemon
avahi-dnsconfd
yum-updatesd

They all now are started by custom scripts in /etc/NetworkManager/dispatcher.d.  Yes
I know that theoretically autofs doesn't below there because it can mount non network
drives, but I don't use that so it is there now.

I can pass some of my stuff along if you are interested.
