@onfy you're supposed to create a partition while installing like every other OS https://wiki.archlinux.org/title/Installation_guide#Partition_the_disks
@noiob And the normal x64 distros I've used are distributed as an ISO you boot from, and that handles creating the partitions on a blank disk for you.
@onfy I mean you also boot from an iso to install arch, then you use fdisk to partition
@noiob Can't say I've found a Raspberry Pi Arch ISO...
@onfy https://archlinuxarm.org have fun!
@noiob No ISOs there but uh, thanks.
@noiob I mean, one of the few things the Raspberry Pi actually has going for it by now, I think, it that normally an OS is just distributed as an image file you can just write to an SD card and boot it right away... What's the point of needing to create a file system?
