@onfy you're supposed to create a partition while installing like every other OS https://wiki.archlinux.org/title/Installation_guide#Partition_the_disks
@onfy fwiw the archwiki guide is really thorough, I've used it multiple times and haven't run into any real problems
you gotta be careful when creating your partitions but that's the case with every installer
@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?
@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've only manually installed DOS before that way, I know DOS much better than Linux and I still needed a guide. I'd be too afraid of messing something up and fscking a production OS.
