Title:
  race condition in USR1 signal handling in mountall

Status in “mountall” package in Ubuntu:
  Fix Released

Bug description:
  There is a slight race condition in the way mountall installs its USR1
  signal handler. It does that after daemonising, so as a result the
  mountall-net job might send it the USR1 signal after the mountall job
  has reached the start/running state but before it has installed the
  signal handler.  This will result in mountall getting killed.

  Example of an automated test run showing this problem:
  http://hydra.nixos.org/build/2309161/log/raw.  The relevant line is:

  client2# [   10.963784] init: mountall main process (1971) killed by
  USR1 signal

  The attached patch (to mountall 2.35) fixes this by moving the
  installation of the USR1 handler to before the fork.
