Adding postmarket OS to multi-distro image
So I finally tried the pmbootstrap tool to create a bunch of
rootfs tarballs for several postmarket OS UI variants: GNOME, Phosh, Plasma
Mobile, fbkeyboard.
I've added them all to my multi-distro image without any increase in size
since the previous public build of the image. So now it's a 13 distro
multi-boot image with pretty much every major and a bunch of minor PinePhone
supporting distributions, and it still fits on a 8GiB SD card!
