Re: [atomic-devel] How to apply non-atomic tuned profiles to atomic host

Because layered products (not just OpenShift) do not want to be coupled to the RHEL release schedule to update their profiles.  They want to own their profiles and rely on the tuned daemon to be there.

I see two aspects to this discussion:

1) Generic tradeoffs with host configuration
2) The specific discussion about tuned profiles

Following 2) if I run:

$ cd ~/src/github/openshift/origin
$ git describe --tags --always
$ git log --follow contrib/tuned/origin-node-host/tuned.conf

There are a grand total of *two* commits that aren't mere
code reorganization:

    Provide both a host and guest profile

That level of change seems quite sufficient for the slower
RHEL cadence, no?

Particularly when one considers that something like the
inotify watch bump could easily be part of a "tuned updates"
in the installer that would live there until the base tuned
profile updates.


Before we go the layered RPM route I just want to make sure you're onboard with it, as I was not aware of any existing in-product users of that feature.  Are there any? If we're the first that's not an issue, just want to make sure we get it right.

In this particular case of tuned, I'd argue that Atomic Host should come out of the box with these profiles,
and that any async updates could be done via the openshift-ansible installer.
