Out of curosity I scanned Obarun Installer at https://framagit.org/Obarun/obarun-install to check what part of the installer is doing the magic to run different commands to enable modules , services and trees but could not locate it .

I installed obarun installer on my current obarun and from that I installed another copy of obarun on an unused partition and the installer installed a fully functional Obarun according to the my needs without any manual intervention needed from my side for the above mentioned commands.

So where is the secret hidden in the installer doing this magic? Can I find it and see how the installer does this job?
