Hey LUG,
Does anyone have a list of tuned tunings or can suggest where I'd find such
a list?
I perused https://fedorahosted.org/tuned/ and https://github.com/redhat-
performance/tuned and haven't really been able to find anything beyond the
statement: "We are currenlty working on many new tuning features. Some are
described in the manual pages, some are yet undocumented." :)

In particular I'm interested in the tunings in /usr/lib/tuned/oracle/tuned.

kernel.panic_on_oops = 1

TIA!
