Just about all arch linux installers out there use the calamares installer. just wanted to highlight the fact that arch linux can be installed from a live environment without the need of calamares. It can be done with the archinstall script from a live environment and you can even have your customizations built in. Down the line I will do a detailed video to explain the files in the lhinstaller folder. for now you can take a look at them and if you follow them correctly you can figure it out yourself. Just remember that this is the file structure you are working from:
$HOME/iso/releng/airootfs/etc/skel/.local/share/scripts/***
I think I'll pass on that! There's always something the archinstall script complains about, the Calamares forces your hands to install in EFI mode whether you like it or not (needless to say which corporation that reminds me of). Vanilla Arch supports MBR installation, Calamares and archinstall don't, Manjaro's installer breaks the MBR of the disk you install it on and if you decide to install something else after Manjaro, you have to run lilo to fix what's broken... WTF happened to the freedom in Linux? I thought it was up to the user to decide what type of installation they want...
With the way things are going with linux and considering Mint is a total crap, I'd rather reformat everything to NTFS and go back to the Windows I hate than having to go through all the trouble and the visions everyone forces on the end user.
