Public bug reported:
[copy paste of https://github.com/sosreport/sos/issues/1844]
In at least version 3.6-1ubuntu0.16.04.3 and 3.6-1ubuntu0.18.04.3, neither the
sosreport process itself, nor (and more importantly) the compression binary are
run with an explicit I/O nice class.
This results in the use of the best-effort class, and can cause serious iowait
on hosts with limited I/O capabilities:
$ ionice -p `pgrep xz`
none: prio 0
$ ionice -p `pgrep sosreport`
none: prio 0
I propose any command sosreport runs to be reniced to use the idle class, or at
least a low-priority best-effort profile.
