All this hoopla about calamares being so great and pretty, all calamares does is copy the live/host system into a target partition, then use chroot scripts to rename user, set hostname, locale, tz, passwords, and once booted you are in the same old system.
Very safe for a distro to make sure everything is functional and boots well, because it is a very fixed model. So you download this month old 3GB fancy desktop image from their site, start calamares up, do an installation and then log into a month old system needing 1.5GB of upgrades, and in the meantime due to upgrades (like if qt or sddm did an upgrade) your system fails to reboot.
But calamares worked great, didin't it. The "warranty" is still valid, it booted once! Then it is all your fault.
Make a 3GB partition, and go to obarun jwm or base, and mount the target to /mnt, then run as root
# cp -ax / /mnt
Get the oldest obarun iso you will find in archive, to do this. All you need to do is rerun syslinux afterwards on the target or grub.
Boot it, root pw toor oblive pw toor ...
That is all calamares does. Maybe Eric can add a console based video player and show rabbits chasing each other in the field while the installation is taking place, and that would make it a graphic installer.
Read the review by DW on archcraft today, then read the review by the same dodo-bird on Obarun, tell me how pissed off one should be.
OOhhh well!! Pay and play, don't pay and sit on the fence looking in. Who is free, those inside the fence or those out?
