 ## Alpine linux
 Recently I switched from raspbian to Alpine to reduce boot time. Tools like [this](https://github.com/macmpi/alpine-linux-headless-bootstrap) really make it simpler to setup. 
-However I was still struggling with gpio permision problems ( [solution](https://raspberrypi.stackexchange.com/questions/40105/access-gpio-pins-without-root-no-access-to-dev-mem-try-running-as-root)  ), and needed to compile lgpio from source ([script](install_scripts/lgpio_compile.sh)), but libiso9660 and libcdio-utils installation wasn't nessesary.
