Changes (by Quozl):

  * next_action:  diagnose => reproduce


Comment:

 considering the possibility that /etc/init.d/halt is called twice:

  * /etc/rc.d/rc treats /etc/init.d/halt to an exec instead of a
 subprocess, so 'rc can't be responsible for calling it twice,
  * /etc/init/rc.conf specifies the execution of /etc/rc.d/rc,
  * there is only one symlink to halt or reboot,
  * that leaves upstart.

 there remains also the possibility that the mount of /etc/adjtime failed
 due to a temporary shortage of some resource.  the mount is not retried.

 i don't think there's much more to do on this ticket until we have a unit
 that reproduces the symptom.  when that happens, we need to:
  * get an image copy of the filesystem using fs-save,
  * see if the problem follows the filesystem or the unit,
  * add temporary code to rc.sysinit to record mount failure,
  * add temporary code to /etc/init.d/halt to report when adjtime is not
 tmpfs.
