Support for system-as-root devices in recovery mode

[valpackett]

Modern devices use system-as-root, so the framework can be in /system/system — while in the recovery at least. I've been doing this:

but proper auto-detection would be better of course :)

Would this make it work on the Samsung S10e? That uses system-as-root with magisk in recovery if I understand what I did to root my phone correctly. I don't know what kind of bounty value would be appropriate but I can definitely post something if this would allow me to add sig spoofing and thus get rid of google services in favor of µG.

It seems that this repository is currently broken since like Android 9, not sure if we also need to change a ton of other stuff and this is futile, or if this would be one of just a handful of things to be done to make it work again for Android 11. In the latter case I would think it's worth it trying to get there.
