Ok.  This is because of the 'console output' line.  If you comment this line
out, do you get this log file on reboot?

The above two lines are not part of the standard mountall job.  Why are they
here?

Ok, so currently this line doesn't show either --verbose or the redirection,
so it's not surprising that no log is created in /run on boot.  Did you try
the line I had suggested?:

      exec mountall --daemon $force_fsck $fsck_fix --verbose >
/run/mountall.log 2>&1

In asking for a copy of this job file, I was hoping to confirm that this
change was made correctly.

Title:
  mountall blocks boot

Status in “mountall” package in Ubuntu:
  Incomplete

Bug description:
  after upgrading to Quantal the system no longer boots.
  I've debugged the issue by booting with init=/bin/bash and it seems that mountall fails to spawn a few processes because PATH is wrong.
  Here is the strace output:

  [pid  3302] execve("swapon", ["swapon", "/dev/sda2"], [/* 9 vars */]) = -1 ENOENT (No such file or directory)
  [pid  3302] execve("/bin/swapon", ["swapon", "/dev/sda2"], [/* 9 vars */]) = -1 ENOENT (No such file or directory)
  [pid  3302] execve("/usr/bin/swapon", ["swapon", "/dev/sda2"], [/* 9 vars */]) = -1 ENOENT (No such file or directory)
  [pid  3302] write(2, "mountall: swapon /dev/sda2 [3302"..., 61mountall: swapon /dev/sda2 [3302]: No such file or directory
  ) = 61
  [pid  3302] write(15, "!", 1)           = 1
  [pid  3277] <... read resumed> "!", 1)  = 1
  [pid  3277] close(14)                   = 0
  [pid  3302] exit_group(0)               = ?

  here mountall fails to spawn swapon, but the same happens to fsck.
