[arch-releng] [RFC] [PATCH 1/3] [archiso] Implement own chroot functions in mkarchiso
* Remove devtools dependency. * Better control over what files are touched inside chroot (root-image). Now: NONE :) * Two new commands: + init: To install {base} group and other needed packages (syslinux for now) + run: If we want to run some command inside chroot (mkinitcpio, locale-gen, useradd, etc etc...) * Renamed command: "created" to "install", says much better what does.

I meant code comments in the code, those are more useful than code comments in an email.

Make build steps much more simply (remove chroot build is not really needed now).
