[Touch-packages] [Bug 1707792] Re: systemd-udevd crashed with SIGABRT in __epoll_wait_nocancel()
*** This bug is a duplicate of bug 1705870 *** https://bugs.launchpad.net/bugs/1705870 ** Description changed: I don't know if this should be considered a bug in systemd or apport. systemd-udevd appears to crash with this bug on each boot.

Starting the system seems to take longer than it should; specifically, once the non- graphical login prompt is shown, it sometimes takes up to a minute for LightDM to appear. But I don't know if that is related, and beyond that, I have not observed anything going wrong on the system. When I originally installed this Ubuntu (guest) system, Apport did not inform me of a crash. Since then, the host system engaged in more intensive I/O, and also I enabled artful-proposed, and now the crash occurs. I don't know if either of these changes are relevant. This most resembles bug 1705870, which occurred in Artful with some slightly earlier package versions. Depending on the results of the symbolic retrace, I might mark this as a duplicate of that bug. It also resembles bug 1663995, bug 1506798, bug 1433320, and some of its (many) duplicates. That bug (i.e., bug 1433320) was considered to affect apport rather than systemd (see https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1433320/comments/10) and is considered fixed. (To a lesser extent, this bug resembles bug 1437896, which that bug mentions, and which is considered a bug in systemd.) I have made /bin/sh a symlink to bash on this system instead of dash (because I am using this system to test http://www.linuxfromscratch.org/lfs/view/development/chapter02/mounting.html, which expects it). Aside from making startup scripts run a bit slower and increasing memory footprint slightly, I suspect this is irrelevant to this bug, but it's a significant (and *unusual*) change so I figured it is worth mentioning.
