Am uploading a new updated iso at the moment. Upgraded kernel and fresh packages.
Have updated mkarchiso (latest pacman version) as archiso no longer supports custom rootfs scripts. Archiso now uses pacman hooks to make minor changes to rootfs (things like locales, timezone, hostname etc). So I created a simple hook that calls custom script. It seems to work. Do have to edit mkarchiso to stop it removing all files from /boot, need to keep micro code and kernel to allow offline install.
Must admit to being behind with archiso source as I did not want to break my build script. Will keep an eye on archiso for any major changes.
Stay safe…
