I thought it was odd that the script would update to an earlier version than the repo, is this possible?
Anyway, one of the problems is the signature problem, but I fought it.
I tried to use the live to make an installation and there was always something that broke it. I tried without updating the script and installer, I tried with an update through the script, and then I tried with an update through the repo. All 3 ended up in disaster.
Then I tried a minimal arch installation, no desktop/wm stuff on. I thought I can convert to obarun and try to simulate what is on live. It worked, a lot of work cleaning up the systemd crap, and still some of the custom work and configuration of artix was hard to reproduce.
So then I tried a 5th experiment,
https://wiki.archlinux.org/index.php/Offline_installation
# cp -ax / /mnt
+ install a kernel + fix /fstab and grub and there it was.
Then you can update and upgrade either through chroot or after booting it.
I am trying to learn how to make an iso so I am trying to stay as close to the original as possible.
One thing I never figured how to make it work is the right click menu on jwm. It comes out with spacefm/root-spacefm options only.
I think a new official iso is needed soon. That # cp -ax /mnt .... I had no idea existed, in debian it was not as easy to do this.
That's a nice option. No network needed, and as long as there is space on /mnt it is pretty failsafe.
