[Bug 802632] Re: udev rule doesn't create or mount /dev/shm

[Steve Langasek]

Jorge,

This has nothing to do with udev, since /dev/shm is not a device; it's
handled via mountall.  In oneiric, this should actually be mounted as
/run/shm, with a /dev/shm symlink created by /etc/init/mounted-dev.conf.

Do you still see this missing /dev/shm problem on current oneiric?  I'm
guessing this may have been fixed sometime in the intervening 3 months
by our work on the /run transition.

** Package changed: udev (Ubuntu) => mountall (Ubuntu)

** Changed in: mountall (Ubuntu)
       Status: Confirmed => Incomplete

Title:
  udev rule doesn't create or mount /dev/shm

Status in “mountall” package in Ubuntu:
  Incomplete

Bug description:
  My system would not boot at all, just freezes when it gets to the
  display manager. James Hunt debugged the laptop and asked me to file
  this bug and then he would add more information.

  Workaround:
  Add "init=/bin/sh" to the kernel line in the grub menu.
  mkdir /dev/shm
  mount -t tmpfs -onosuid,nodev,noexec none /dev/shm
  exec /sbin/init

  Oneric up to date as of 27 June on a Thinkpad X220i
