After several successful manual Arch installs, I tried to use the `archinstall` command from the Arch Linux ISO image.
I created just one EXT4 partition, and configured its mountpount to /mnt. Also made it bootable. (type: primary, start at 1024B (the default), size "100%") Hit save and exit.
When I start the installation it says "parted ended with bad exit code: 256". "The closest location we can manage is 1024B to 512MB..."
Usually you do not need a "boot" partition and you should be able to just go with one EXT4 partition. I did that in the manual install by just using fdisk and use the default values by hitting Enter.
Does someone know how to use a single EXT4 partition in the arch installer?
