What does the FR stand for in FR initrd?
I see that used a lot.
Thanks

It's the initrd used in all current Kennel Linux related builds, which are created using FirstRib (FR) build script system (not based on woof-CE). The initrd is what gives the layering functionality. FR initrd is a general purpose initrd (can be used to boot most any root filesystem) that has always employed overlayfs since its design in early 2019. It has no relation to Puppy initrd design, or DebianDog modified Porteus initrd design, though all of these can provide some similar key functionality (but not identical functionality).

Thanks for that explanation.
I have a long way to go to understanding all of this, but I'm appreciating this thought of layering. It's an amazing way to make these systems to work so well. Now I think I understand that there are different ways to do this as well.
