Thank you @balbes150 for askting sfs about clean rootfs. Well i just point what are archlinuxarm goals:
We are a port of Arch Linux, which aims for simplicity and full control to the end user. We provide a light-weight base structure that allows you to shape the system to your needs.
So maybe sfs can create such image to be dd to mSD card which is just lit-weight base, and then his repository so the one can install what ever he would like.
I know pacman -R can delete stuff but why to have them installed at all.
I'll try to use sfs release but an almost as "archlinuxarm" image would here be preferred.
I don't understand why Khadas is going with *buntu at all..
