The bug was apparent in 13.10, but I do not see it after upgrade to 14.04 (amd64). I do not see dhclient in lsof output but I have not check with ps.

Not sure it's an upstream bug - if you read back, there used to be Debian-specific code wrapped in an #ifdef, which depends on a preprocessor symbol that is no longer defined .. if you've got time you could see if the seem problem ever existed in Debian, and if so, if/how they fixed it ..

OK, the commit that fixed things for me was upstream commit 52b3810b0e0d87bb47c6d77627d49fbb323d804d, "fix NMPolicy/NMManager refcounting." Not familiar with exactly how git works, but that seems to have been cherry picked and reapplied to the main branch as 8c167c1f8f4338ccdc9906a9595e02c67fc1d9ca: http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=8c167c1f8f4338ccdc9906a9595e02c67fc1d9ca Somewhere between 0.9.8.2 and 0.9.8.4.

Looking at this now, and getting sidetracked by RCS confusion .. what is the difference between: http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/trusty/network- manager/trusty/files and http://bazaar.launchpad.net/~network-manager/network- manager/ubuntu/files ? The latter seems to have the up-to-date code that I get when I "apt- get source" on trusty, no idea what the former is..

I'm using raring and also having the issue of shutdown/restart hanging for a short time due to "mount: / is busy". I made a script that executes "ps -Af" on shutdown/reboot and writes it to a log file. (see attachment) There's a long line containing "/sbin/dhclient"; I presume that indicates dhclient being the root cause? ** Attachment added: "log file of ps -Af during shutdown/reboot" https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1169614/+attachment/3743585/+files/process.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1169614 Title: /etc/init.d/umountroot: "mount: / is busy" due to dhclient is not stopped To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1169614/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

** Summary changed: - dhclient is not stopped during shutdown + /etc/init.d/umountroot: "mount: / is busy" due to dhclient is not stopped ** Description changed: The result is "mount: / is busy" and root filesystem recovery during next boot. network-manager 0.9.8.0-0ubuntu3 in Raring neither stop dhclient in response to "stop network-manager" nor remove pid file from /run/sendsigs.omit.d/ So dhclient skipped by /etc/init.d/sendsigs and a lease file is open for writing in /var/lib/NetworkManager while /etc/init.d/umountroot is running. As a consequence root filesystem can not be cleanly remount readonly before poweroff. In default setup the problem is hidden by plymouth.
