[Bug 575940] Re: Enforce CONFIG_TMPFS_POSIX_ACL=y for proper /dev perms

[Leann Ogasawara]

** Description changed:

+ SRU Jusitification:
+ 
+ Impact: Without this change, a flavour may be created without
+ POSIX ACL support in /dev. This prevents some devices from
+ functioning.
+ 
+ How Addressed: The change adds an enforcement statement.
+ 
+ Regression Potential: This is a build system change, so as
+ long as the kernel builds there is no regression.
+ 
+ =====
+ 
  Ubuntu 10.04 (and possibly earlier releases) requires POSIX ACL support
  for some /dev nodes. For example:
  
  cndougla at mini:~/Canonical/ubuntu-lucid$ getfacl /dev/dsp
  getfacl: Removing leading '/' from absolute path names
  # file: dev/dsp
  # owner: root
  # group: audio
  user::rw-
  user:cndougla:rw-
  group::rw-
  mask::rw-
  other::---
  
  I know that at least sound is broken without CONFIG_TMPFS_POSIX_ACL=y,
  so we need to enforce it for all flavours.

** Also affects: linux (Ubuntu Lucid)
   Importance: Undecided
       Status: New
