I’m aware that a multiboot (i.e. having two mobileOS installed) is possible, depending on a modified recovery (aka TWRP), and by using both A/B partitions sets on compatible devices.
So, my questions are :
1- Does UT use both A/B partitions when doing an OTA-update ? (for the devices having A/B partitions of course), or does OTA-update use only one set of partitions anyway ? (cf. legacy devices)
I saw on a multiboot-tutorial that a specific build of UT was needed for multiboot, and that OTA updates then becomes unavailable. Which leads me to my last question :
2- What are the needed features and their tradeoffs for UT to be multiboot-compatible by default ? (i.e. to have the same UT as everyone, with OTA-updates, on a multiboot device)
