      I'm adding this here so that it's more obvious. Build a boot.iso using the new `--rootfs-type erofs` argument, confirm that it boots and that the rootfs that is mounted is erofs not squashfs.

      At this time (8/14/2024) the kernel erofs drive does not support compression so there is no point in testing until the kernel has been updated.

       

      As of 1/21/25 the kernel supports lzma compression and not zstd. lorax-40.5.11-1 uses lzma when `--rootfs-type erofs` is passed to it, so this is ready to be used for building the nightly boot.iso

      Add support to lorax to allow selecting the type of root filesystem used for the boot.iso
      This has been implemented upstream in lorax-41.2-1 and adds a `--rootfs-type` option to lorax allowing the selection of the current squashfs only style as well as the new erofs compressed filesystem.
