NetworkManager 0.9.8.0 from Raring is not a solution.
It use /var/lib/NetworkManager/ directory to store .lease
files. It is not allowed by apparmor policy
isc-dhcp-client: /etc/apparmor/init/network-interface-security/sbin.dhclient
If permissions for /var/lib/NetworkManager is granted to
Ernie, you have faced another bug in NetworkManager.

or someone should open a dedicated bug.

In 12.10 Quantal NetworkManager 0.9.8.0
After I replaced network-manager with wicd on 12.10 everything works
perfectly. Now shutdown is much faster -- no delays at all. And I got
rid of the hacked init scripts that I was using to circumvent the bug.
Thanks for mentioning wicd, Russell.

Ernie, have you tried temporarily replacing NM with wicd on 13.04? (See
https://help.ubuntu.com/community/WICD)
When I use wicd, there is always a clean shutdown, without any delays.
On my 12.10 installation using NM 9.6.0, I can get clean shutdowns by
unchecking 'available to all users'.
Russel, have you tested network-manager 0.9.8.0 and related
libraries form Raring or just network-manager 0.9.6.0
rebuilt with the following patch?

I expect that it should work with always enabled network

Max, I have not tested either. I am using the latest 12.10 version
(0.9.6.0-0ubuntu7).
I would be happy to test further. Is there a binary version available of
0.9.6.0 with the patch you mentioned?
BTW, my machine shuts down in 5-8 seconds using wicd, compared with
20-25 seconds with NM
Ernie, I can confirm that 12.10 with original network-manager
0.9.6.0 has this problem and it appears during shutdown.
I do not play with unchecking of networking, it is always enabled.
The patch mentioned in the comments fixes the issue for me.
Another option is to install to 12.10 the
Max,
I have given up on 12.10 but would like to make use of 13.04.
The Raring daily amd64.iso contains network-manager version 9.8.0 and it
exhibits the same failure pattern as 9.6.0 in 12.04.
The failure is 100% reproducible and will manifest each time the OS is shut

I do not see any problem with busy /.
NetworkManager 0.9.8.0.
The only minor issue is 10 seconds pause during shutdown
due to /etc/network/if-post-down.d/avahi-daemon,
but it is likely caused by the provider and his
subdomain in .local zone. Root
I strongly believe this problem is associated with termination rather
than startup.
I can establish conditions for failure by checking enable networking or
prevent failure by unchecking enable networking prior to reboot, restart
or shutdown.

From the upstream report [1], the patch that resolves this regression
has been applied to networkmanager's master branch, so Ubuntu needs to
carry this patch until it is included upstream:
