Here is the file:

# This helper mounts filesystems in the correct order as the devices
# and mountpoints become available.

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.
