[Bug 1121699] Re: aufs CONFIG_AUFS_EXPORT build option should be enabled

 

I did some research - CONFIG_AUFS_EXPORT=y in the following kernels for Ubuntu 12.04.5:
   linux-image-generic-lts-trusty (linux-image-3.13.0-36-generic),
   linux-image-generic-lts-saucy (linux-image-3.11.0-26-generic),
   linux-image-generic-lts-raring (linux-image-3.8.0-44-generic),

and not set in:
   linux-image-generic-lts-quantal (linux-image-3.5.0-54-generic),
   linux-image-generic (linux-image-3.2.0-69-generic).

So the fix is needed for 3.2 and 3.5 kernels in Ubuntu 12.04. Please
release it.

Title:
  aufs CONFIG_AUFS_EXPORT build option should be enabled

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Raring:
  Fix Released

Bug description:
  This is needed to export aufs filesystems via nfs.

  This was set in a previous version (in Debian - http://bugs.debian.org
  /cgi-bin/bugreport.cgi?bug=490079), and released in Ubuntu build for
  aufs 0+20080719-4
  (https://launchpad.net/ubuntu/+source/aufs/0+20080719-4), so this
  could perhaps be considered a regression (although to be fair aufs and
  its packaging has undergone significant rewriting since then).

  Regardless considering aufs is a popular method of supporting large
  storage systems (among other things) and nfs is a popular method of
  exporting large storage systems, it would be great if this could be
  enabled in a future build, unless there is some known
  contraindication.
