I too am unable to recreate this problem - dbus should certainly not be running in recovery mode because dbus is 'start on local-filesystems', but that event will not have been emitted since mountall is not run in recovery mode.
Can you confirm you are entering recovery mode from the grub menu (Advanced options -> recovery)? Can you also check the following: 1) Enter recovery mode. 2) Select the root shell option. 3) Run "set|grep UPSTART". What you should see is: UPSTART_EVENTS=recovery UPSTART_INSTANCE= UPSTART_JOB=friendly-recovery Can you also check that you don't have an /etc/init/dbus.override and that your /etc/init/dbus.conf is unmodified - running 'apport-collect -p upstart 1348784' will do this for you. Attaching the output of 'ps -efwww' and 'initctl list' from recovery mode could also be useful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1348784 Title: thermald prevents unmounting /dev/sda1 in recovery mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/1348784/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
