Comments in extra packages?

Hello!

I've been following @castrojo 's journey for a while now, love your work ❤️ This is an incredible project along with the toolbox images, silverblue and everything in between!

Small QoL thing people might find useful I've done for my own distrobox building as I'm playing with it:

RUN apk update && \
    apk upgrade && \
-    cat /extra-packages | xargs apk add
+    grep -v '^#' /extra-packages | xargs apk add

Which just allows me to comment out lines in the extra-packages file while I'm building locally and messing around 😊

Thanks! If you've got more fixes feel free to send a PR!
