Description Daniel Drake 2012-05-03 13:45:10 UTC 
OLPC runs / as a bind-mount for reasons explained here:
http://lists.freedesktop.org/archives/systemd-devel/2012-April/004961.html

The code in umount.c (systemd-44, git as of today) currently skips bind mounts and we're not sure why.

This means that / is left mounted RW on shutdown and we experience some disk corruption here and there.
