[Group.of.nepali.translators] [Bug 1550301] Re: ZFS: Set elevator=noop on disks in the root pool
Since this affects root on ZFS and the original patch no longer applies (and ZFS on root) is not currently supported, I am reluctantly going to close is issue. If a clean fix for ZFS on root for newer Zesty+ initramfs scripts is available I am happy to re-apply them for newer releases. However, I am not going to forward port the original changes since the delta is too large and I am not able to test these (as we don't have ZFS on root by default). ** Changed in: zfs-linux (Ubuntu Zesty) Status: Confirmed => Won't Fix ** Changed in: zfs-linux (Ubuntu) Status: In Progress => Won't Fix -- You received this bug notification because you are a member of नेपाली भाषा समायोजकहरुको समूह, which is subscribed to Xenial.

For a root pools, it's just the opposite. The typical case is that partitions are used. And, for root pools, it is unlikely that the same disks have non-ZFS filesystems. The debdiff in comment #5 applies cleanly to the latest package and functions correctly. This is an important change for root-on-ZFS users. It has no effect on non-root-on-ZFS installs, because the code is only in the zfs-initramfs package.
