script.

Title:
ZFS: Set elevator=noop on disks in the root pool
Status in zfs-linux package in Ubuntu:
Confirmed
Bug description:
ZFS-on-Linux has its own I/O scheduler, so it sets the "noop" elevator
on whole disks used in a pool.
https://github.com/zfsonlinux/zfs/issues/90
It does not set the scheduler for a disk if a partition is used in a
pool out of respect for the possibility that there are non-ZFS
partitions on the same disk.
https://github.com/zfsonlinux/zfs/issues/152
For regular pools, the recommendation is to use whole disks. 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.
