No-go. According to the syslog, the segfault has not happened since I reconfigured the kernel and startup sequence two days ago to resolve an XFS mount issue. Something in there changed the init timing just enough to make it go away, I believe. Now I'm blowing it all away in favour of fresh userspace, with a whole new set of issues to resolve. :) Off-Topic: Ubuntu (Mythbuntu) really has a ton of timing issues with this upstart thing at startup and shutdown.. running from an SSD really exposes the flaws.
