CAOS (Custom AOSP OS) is a project which based on [MENTION=1915408]phhusson[/MENTION]'s Treble GSI AOSP 10. I began it because original project have not only pros (stability, speed, support) but also some issues and limitations - pure AOSP code have some bugs / haven't much useful things and it's a hard way pulling it. So i did this fork. System can run with SELinux enforced state, as an original Phh AOSP GSI. Fully compatible with PHH-Treble patches exclude few low level changes: no root app, no "su" binary in system; by default exist file /system/phh/secure (for Google Certification PASS), so if you can boot AOSP GSI, but can't boot CAOS - try to removing that file

vanilla, gapps: all architectures

gapps-go: only ARM A-only

NAMING

Some information you should know about knowing what type of gsi it is

<ARCH>_xyZ

<ARCH> can either be arm, a64 (arm32_binder64) or arm64

x can either be a or b

y can either be v, o, g or f

Z can be N or S

b = a/b

a = a-only

g = gapps

o = gapps-go

v = vanilla (no gapps included)

f = floss (free & open source apps instead gapps)

N = no superuser

S = superuser included

so in most common example "arm64_avN" is ARM64 A-only vanilla with no superuser
