build-release.sh builds the Pi image and the MT6000 root + FIT into release/guix-router-DATE-REV/ (zstd), with both installers, checksums of the compressed and uncompressed images, BUILD-INFO and INSTALL.md. install-mt6000.sh installs a release on a GL-MT6000 with stock U-Boot: it serves OpenWrt's official initramfs (downloaded, checksum-pinned) by TFTP in the sysupgrade form GL's U-Boot accepts, waits for the power cycle, writes p7/p6 from the OpenWrt running in RAM, verifies both and reboots into Guix. flash-rpi.sh takes .zst images.
