The resolution to the segfault in olpc-dm turned out to be obvious.
XSCE developers have responded to on-the-ground requests for teamviewer,
and added it to the ansible playbook, without realizing that it is not
compatible with olpc-dm. Teamviewer daemon was being pulled in by
graphical.target.

I missed one obvious clue, thinking that Xorg.log was the strategic place
to look.
/var/log/messages (search olpc-dm) shows
- "olpc-dm.service holdoff time over, scheduling restart"
- and then "xauth: file /var/tmp/olpc-auth/.Xauthority does not exist"
googling "Xauthority create olpc" doe
I'm interested in finding the cause; any such race condition that
prevents X startup may eventually occur depending on timing, so is
there some simple reproducer that we can apply to OLPC OS?
Where are your changes relative to OLPC OS?
What does the systemd journal say about olpc-dm service?
