1) Armbian focal (or any good/stable desktop environment that allows me to use a wacom tablet I have, tested official ubuntu and despite the wacom driver present in the kernel , it didn t work ad hoc)
2) Android (tried the official one so far but not succesful )
3) Batocera (to avoid configuring too much in the linux desktop environment)
3) OpenElec (optionnal since I am unsure if there would be any benefit against installing kodi on a linux desktop environment)
So apart from my usecases I am interested in undertanding how this whole partition/booting works here.
I have petitboot 20201020 flashed on SPI at the moment and it is pretty great to be able to use only the remote to select any kernel).
I have attempted to adapt the dualos_compose.sh for my purpose and not sure first if my code is 100% correct (I have a doubt in the amount of partitions).
Code: Select all

1) Official ubuntu mate : seen by petit boot and booting
2) Batocera : seen by petitboot and booting
3) OpenElec : seen by petitboot not booting properly
4) Official android : not seen by petitboot (I undesrtand here the autoinstall wont work anyway adhoc)
5) Armbian focal : not seen by petitboot.
Best Regards
thx for the support bro
