i guess i was rather vague because i know that it's essentially a mess and how much you can save depends largely on how the app decides to save its config and so on, on the manufacturer and hos the system settings are saved and so on. so i guess that my question was more like, has anyone managed to do android dotfiles in a meaningful way beyond termux? i agree i was sassy but i thought the previous comment was being smug. i have never heard of anyone mention dotfiles outside of this use, so i guess that's a bad on me.
i think the stuff i'd like to backup the most would be some sort of declarative list of installed apps, if possible some system wide settings althought with how messy phones are with settings i doubt it, and maybe a couple of special per app settings. do you know if this is easier of Oses like graphene o lineage?
