Thanks Lennart - good point about the strace being killed before the interesting bit... This makes it annoyingly tricky to see what is happening as the systemd-219 binary gets loaded... Screenshot has been attached to the bug: https://bugzilla.redhat.com/show_bug.cgi?id=1185604#c22 Doesn't show much though - just a SEGV reported by pid1 that immediately results in execution being halted. Tried to put together a reduced testcase via a yum installroot style container to switch-root into to see what that behaviour is like and do see a segfault - not certain if this is the same being seen during the fedup switch-root though... Any ideas to get a better grasp on this? _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
