[Bug 1365874] Re: Ubuntu 12.04 LTS, 14.04 LTS, 16.04 LTS do not support ext4 metadata checksumming

[Marc Peña]

That's great Simon! I will test it once it's ready then.

Regarding (b): wouldn't it be easier to try to get the package in xenial-backports then?
That repo it's activated by default, but as I can read here: https://help.ubuntu.com/community/UbuntuBackports

On releases before (but not including) Ubuntu 11.04 (Natty Narwhal), apt
defaulted to always installing packages from Backports. On later
releases, apt only installs packages from Backports when they are
explicitly requested.

So the risk would be much lower.

Title:
  Ubuntu 12.04 LTS, 14.04 LTS, 16.04 LTS do not support ext4 metadata
  checksumming

Status in e2fsprogs package in Ubuntu:
  Triaged

Bug description:
  In the Trusty release notes "Metadata checksumming" is listed as one
  of the tech highlights of kernel 3.13.

  https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes#New_features_in_14.04_LTS

  However, the userland tools do not support this kernel feature. To the
  best of my knowledge this will be supported in 1.43, and won't be
  backported to 1.42.

  IMHO this is very misleading. It's like a car salesperson sold you a
  sports car with an V8 engine. After you drove it home, you opened the
  hood and realized only 6 cylinders are working because 2 of the spark
  plugs were not included, and you have to buy aftermarket ones.

  <rant>BTW, I've been following the development of e2fsprogs for over a
  year. 1.43  release has been in limbo for God knows how long :(
