linux-live VS meta-raspberrypi

Cubic just doesn’t work for me I have such big problems with KDE plasma and cubic probably works great with gnome I am trying this out https://www.linux-live.org or their git https://github.com/Tomas-M/linux-live

i never tried it but linux-live might be good

It does seem possible: https://www.linux-live.org/. I've been eyeing a custom live ISO, but haven't run through the process myself. That being said, I'd agree with u/doc_willis for the use case at hand.

Turning your installation into a bootable .iso isnt that difficult. That can easily be done with linux live kit.

Best/Simplest solution I ever have used was 'MX Live USB Maker' from and only for 'MX-Linux' (an other nice Debian/Ubuntu/-fork, but not primarily made for games). 'Linux Live Kit' (www.linux-live.org) should do the job too - have not tried yet and can't tell something about that.

there's an iso maker for it

Why not try it and report back?

How do you figure Pis have bad integration with Yocto?

For what it's worth, the entire Pi lineup is also well supported by Buildroot. In-tree, no less.

Embedded linux exactly. Major OEMs are using yocto. Check https://www.yoctoproject.org/

Been there. You don't want alpine or debian. Good gpos, but what you want is Yocto, which will let you build exactly and only what you need piece by piece including only the kernel modules for your hardware, the exact applications you use and no extras, and with a little extra tweaking, you can wire in Mender for ota updates and the ability to push custom images to clients that need specialization, or even fully unlocked images for customers that need it, plus if you're using an SD card, you can send users recovery drives instead of shipping full devices or let them build their own images without your proprietary code

I second Yocto. It's the kernel in use by the OpenBMC project

One last "option" is yocto but tis is not good for desktop, but it can be a fun project.
