[Bug 978032] Re: partitioning step doesn't have "discard" as a selectable mount option

[Colin Watson]

This failed verification for me earlier today: the debconf templates are
missing so no mount options at all are selectable for the affected
filesystem types.  As soon as git.debian.org comes back I'll check
whether Debian has fixed this and amend the package in precise-proposed
accordingly.

Bug description:
  SRU justification:
  [Impact] The installer does not support selecting some commonly-used mount options for common file systems.  While this is technically a feature, the fix consists of adding lines to a plain text file, and it's cumbersome for users to work around otherwise; I'd like to make the trivial changes to precise to add these.
  [Test case] Confirm that the installer permits selecting "discard" for ext4, fat16, fat32, and btrfs.  (Use apt-setup/proposed=true while this change is still in precise-proposed.)
  [Regression potential] Confirming that installation otherwise still works should be sufficient.

  Original report follows:
  Doing a clean install of Ubuntu server on a machine with an SSD. I am led to believe that in my fstab I should add the mount option "discard" to enable trim support. During the partitioning step I manually configured my partitions and selected "mount options" but 'discard' was not listed. I will now have to manually edit my fstab to add this in. Would it not be prudent to have this as a selectable option in d-i for server/alternate images?
