Updates FAQ as above.

Motivation and Context

How Has This Been Tested?

sudo systemctl restart strongswan tested on Ubuntu 18.04.1 server on Amazon Lightsail. It works, and systemctl status strongswan doesn't give an incorrect status.

No idea why the cloud-init build fails...

Just a guess, but it looks like the test script is trying to download the new install.sh script from your forked branch rather than from master, but your branch is a little behind and the script isn't there.

Ok, what do I do to catch it up? I just caught the master branch of my fork up to the upstream master. Should I merge the upstream master into this branch as well?

Last time I tried doing this it looked like I was trying to merge 880 commits all over again...

I'm not confident enough in my git skills to say for sure. This could be totally wrong:

git fetch upstream
git checkout faq-adblock-bypass
git rebase upstream/master
git push -f

It got me close enough that I could google the rest of it (I needed to also git reset --hard to get rid of local changes). Looks like the checks passed now. Thanks!
