    Using 'config-1' configuration
    Trying 'kernel-1' kernel subimage
      Description:  ARM64 OpenWrt Linux-6.6.45

-From the output above it looks like the device I have plugged in has
-an openwrt "recovery" image but not a "production" image
-
-It also looks like it will be quite hard work to persuade it to boot
-from usb or anything. It doesn't have any of the extlinux stuff
-but it does have uefi for what that's worth
-
-default boot_production command reads a ubi volume called 'fit' and
-calls bootm on what it finds
-
-we could define boot_production to ubifsmount liminix; ubifs load
-<addr> <filename> (which is a fit) and bootm it. *presumably* we could
-do this from the openwrt recovery image
-
-but could we install the whole system using said recovery image?  I
-expect we could do, it only requires getting a tarball onto it and
-unpacking it
-
-however, extlinux is not going to be helpful
-(actually it might be a bit, if we ask it to write the fit as
-well as/instead of the individual files)
-
-maybe we need separate concepts of "the filesystem contains
-stuff we need for boot" and "the stuff we need is the stuff
-that extlinux needs"
-
-each bootloader makes an output called bootfiles, and
-the bootablerootdir output copies from bootfiles
-
-Mon Dec 23 18:28:50 GMT 2024
-
-it might be worth moving ubi option decls into the hardware module, if
-they're hardware-dependent
