OK On further investigation, I have confirmed a lot of key-facts (1 of 2 linked comments).
e2fsprogs 1.44.0-1 backports to xenial with no difficulty whatsoever, passes "make fullcheck" and works in every way I can tell, lots of resizing and checking and use within gparted, etc, all (apparently) behaving... HOWEVER, for an official xenial-backport (and especially xenial-SRU), to minimize possible problems, I would highly recommend making single change of restoring the 'default' mke2fs.conf EXACTLY (byte-for-byte) as that which came with xenial e2fsprogs 1.42.13-1ubuntu1 :- https://www.iremonger.me.uk/noidx/e2fs/mke2fs.conf.xenial This (a) avoids prompting users who've customized their mke2fs.conf about merging-changes, and (b) avoids functional-change for those with automated-deployment-scripts etc. based upon ext4 creation. I presume, a 'xenial-backport' -or- SRU "proposed" update can be started straight-away? xenial-SRU should DEFINITELY be considered for fsck compatibility with bionic-created FS. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to e2fsprogs in Ubuntu. https://bugs.launchpad.net/bugs/1365874 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 :( </rant> To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/e2fsprogs/+bug/1365874/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
