The problem isn’t OE per se but every vendor pulls in their own janky patches for everything and you find yourself fighting the build system to cut packages and reduce the filesystem size. It’s also really slow and it’s frankly massive, requiring tens or hundreds of gigabytes of stuff to yield less than a gigabyte of system image. And at the end of the day if a vendor breaks something from another vendor you will find yourself struggling to figure out why. Older versions of their documentation make statements that small teams should avoid Yocto for these reasons.

If you don’t already know anything about how to do these things in Linux Yocto is good for it. But if you try to swim against the current of the way the layer authors want you to do any of those things you will find it very challenging.

Take read-only root, for example. Usually it’s a one-line change in a config file plus an additional mount should you want an overlay in volatile memory. I don’t see how pulling in layers and config files does anything other than obscure how that works.

For a good example of what I hate about it, try building from Meta-Intel without graphics drivers.
