Looks good other than the RTD build and one question about configuring chrony.
| #. *Optional:* If PPS is not working with chrony, ``chronyc sources`` will look similar to below, | ||
| with an "x" next to PPS: :: | ||
|
|
||
| MS Name/IP address Stratum Poll Reach LastRx Last sample | ||
| =============================================================================== | ||
| #x PPS 0 4 7 9 +465ms[ +465ms] +/- 376ns | ||
| ^- tick.usask.ca 1 10 377 493 +921us[ +929us] +/- 16ms | ||
| ^* tock.usask.ca 1 10 377 554 -795us[ -788us] +/- 15ms | ||
|

||
| In this situation, the PPS signal is offset from the expected clock by 465 ms. To account for | ||
| this, modify the PPS line in ``/etc/chrony.conf`` as shown below. Adjust the offset to match | ||
| what is shown in the ``chronyc sources`` table. :: | ||
|
|
||
| refclock PPS /dev/ppsx refid PPS offset 0.465 | ||
|
|
||
| After restarting chrony, the sample should be in the microsecond range, instead of milliseconds. | ||

Would this be fixed by restarting the computer instead of setting an offset for chrony?

Restarting didn't fix the issue when I was testing. The root cause might be my configuration of the PPS card within the computer, I haven't confirmed this though. This fix is a little jank but it works

This is breaking the ReadTheDocs build
|
Path for swappiness value write has changed, file should be made at |
|
Actually I think I may be wrong, the old path might still be valid. Information online doesn't seem to be specific to openSUSE 16.0, there looks to be multiple places that sysctl looks for configuration values. |
Added instructions for preventing computer hibernation

Recently installed Borealis on a pair of OpenSUSE 16.0 machines, this PR reflects changes I needed to make while installing.
