Paul, is it possible that you hit bug #672177, which causes / to not be unmountable whenever upstart or libc6 is upgraded? As to your hypothesis that it was logs, rsyslog *should* be stopped by the time /etc/init.d/umountroot runs, though there's actually no guarantee as the SIGTERM is sent/received/executed in parallel with the rest of the shutdown. That is bug #688541, but I think sounds less likely. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/579858 Title: umount segfault on shutdown when unmounting autofs mountpoint -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
