Yes, but doing that across all of Fedora is pointless. What works
the majority of Server users won't necessarily work for Cloud or
Workstation. Also, the end user's ability to even discover that it's
tunable varies greatly from one Edition to the next. One could expect
sysadmins knowing about this and changing the default on their Server
install. The Workstation end user may not be as low-level detail
aware and could just suffer with poor performance because they think
that's the only option.
Well, I'm starting from Michael's premise that deadline would be better
for latency for most desktop users (regardless of disk type), and
clearly better when using SSD. This leads me to a different conclusion
than the above.
It's irrelevant for cloud and any other virt deployment of Atomic or
Server. As far as I know, the special case on hardware where cfq is
better is the one I outlined (on hardware, single spindle, prefer
throughput, mixed workload) and I agree that it's okay to expect
sysadmins to handle that.
