Sorry to necro this but I’ve been away.
I dont think you are right about GPT and EFI - you can have a standard
Android install using stock grub menu in the qube. I do this on a Debian
minimal install to test different Android versions.
The only issue (but it is a major one) with Bliss is the failure of NIC
drivers - this is a relatively recent change . Otherwise everything
works as expected.
