The build einvironment for the alpine variant is available from here https://github.com/j0ju/sbc-fw-alchemy ideas, bugs an patches are welcome. I recently added some stub docs https://github.com/j0ju/sbc-fw-alchemy/tree/main/docs/TuringPi2-Alpine IMHO for me it is currently far more useful and feture rich than the official FW. * VLANs seem to work * apk - the alpine package manager is avail. * I can have even dev-tools on it, for python ,.... * It might be smaller as it uses musl instead of glibc.
