To overview (when updatable)
- It is very hard to spot a difference in versions so versions are now regarded as commit messages (after dash [-]) when applicable
- This will result in more clear, understandable text
- Bleeding edge (canary) user would see:
ffed229 > ffe02ed or 19.4 > ffe02ed
as opposed to:
19.4-ffed229 (19404)
19.5-ffe02ed (19501)
- Regular beta+ user would see:
19.4 > 19.5
To bottom of the screen
- This change is with respect to regular user. They don't care which version they run as long as they know that "up-to-date" is a gold standard
- It takes tons of real-estate on the screen which takes away the glance-ability from the overview.
This change is made so logic is not placed within the "old" base substrate. Changes made in the redesign could potentially affect the already working part which we obviously do not want.
The state of ROM A/B OTA addon.d-v2 support is an inconsistent mess currently:
- LineageOS builds userdebug with permissive update_engine domain, OmniROM builds userdebug with a more restricted update_engine domain, and CarbonROM builds user with a hybrid closer to Omni's
- addon.d-v2 scripts cannot function to the full extent they should when there is a more restricted update_engine domain sepolicy in place, which is likely why Lineage made update_engine completely permissive
Evidence for the above:
- many addon.d-v2 scripts only work (or fully work) on Lineage, see below
- Magisk's addon.d-v2 script would work on Lineage without issue, but would work on Carbon and Omni only if further allow rules were added for basic things like "file read" and "dir search" suggesting these ROMs' addon.d-v2 is severely limited
- Omni includes a /system/addon.d/69-gapps.sh script with the ROM itself (despite shipping without GApps), and with Magisk's more permissive sepolicy and no GApps installed it will remove important ROM files during OTA, resulting in a bootloop; the issue with shipping this script was therefore masked by Omni's overly restrictive update_engine sepolicy not allowing the script to function as intended
The solution:
- guarantee a consistent addon.d-v2 experience for users across ROMs when rooted with Magisk by making update_engine permissive as Lineage has
- hopefully ROMs can work together to come up with something standard for unrooted addon.d-v2 function
