IDEA: Production Mode

[JBBgameich]

Differences to current version:

• Install rootfs to /system not as an image to /data, but directly on the system partition
• /data is also mounted as /home to save space on the system partition

Some additional info:

• System Image still stays on /data/system.img

Changes needed:

• hybris-boot: look if a debug image exists in /data/rootfs.img and if not, mount /system as /target
• halium-install: img2simg rootfs.img rootfs.sparse.img
  (Does a system image need to be in a special format like a sparse image for fastboot?)

This would probably be an important feature for phone manufacturers, like StationX, as it uses the available space more efficient.

It's also often quite painful to transfer huge files using adb in TWRP. This would be using fastboot for flashing the rootfs.

Please leave some feedback on if you see any problems or if I forgot something.

I'd appreciate that solution, it's far more easier and clean, I think.
There's only one problem, you're limited to 2 GB (in my case) with the rootfs. If you want to install some global deb packages, you'll reach that limit very fast.
Installing deb packages into ~/.local/ would be very cool, but that's out of scope of halium.

I did a untested implementation of this here: Halium/hybris-boot@master...JBBgameich:POC-production
