Xa2 instructions

[AlexEdimensionz]

• IP tables command can't be executed if rsync already running. Reversed the order
• The revert process is different (easier) for t he XA2

[rfvermut]

I'm reluctant of merging XA2 specific code here.

• I cannot test is right now
• It's already a bit of the mess with --env LXC and if's inside code

What I propose:

• This repo stays as pure Android 4.4 patch and I will update README to reflect it
• @yeoldegrove fork will focus on new Android 8.1 LXC and remove everything non-LXC
• We build and publish docker images into DockerHub. Because I feel git submodules and internal make introduce unnecessary complications for users, and my goal was to make it as simple as ever possible.

@yeoldegrove WDYT?

[AlexEdimensionz]

My pull request doesn't remove the existing instructions. i added a section at the bottom for XA2

@AlexEdimensionz You can create a PR against https://github.com/yeoldegrove/sailfish-signature-spoofing-lxc against the master branch. We can merge this there.

@rfvermut I like your idea of splitting it up... Makes it more easy to maintain.

@yeoldegrove what would be the good telltale of LXC environment? So I can add it to script like

if [[ -f /etc/LXC ]]; then
  echo "Seems like you are using tool for older Android version. Please use yeoldegrove/sailfish-signature-spoofing-lxc"
  echo "https://github.com/yeoldegrove/sailfish-signature-spoofing-lxc"
  exit 1
fi

@rfvermut
test -f /var/lib/lxc/aliendalvik/config should be enough

By the way... Funny this is going so fast and we both already have everything up and running ;)

@AlexEdimensionz I opened a new PR for you here: yeoldegrove#7

Nothing can stop SFOS.

I added simple validation: f35aa89#diff-1b0c2b516b83393edb7200ad5ff12181R6
