I'm fairly new to linux but decided to dive right in with arch-linux to become familiar with everything. Unfortunatelly I can't even finish the installation - shame on me.
The error while booting after setting arch up is:
ERROR: Root device mounted successfully, but /sbin/init does not exist. Bailing out, you are on your own. Good luck. I went for btrfs on luks on lvm
The layout looks like this
sda |- sda1 512MB fat32 /boot `- sda2 remaining lvm |- cryptswap 4GB swap |- crypttmp 2GB tmp /tmp `- cryptroot remaining btrfs |- @ / |- @home /home |- @snapshots /.snapshots |- @log /var/log |- @cache /var/cache `- @tmp /var/tmp Those are the commands and configurations I used to setup arch:
dd status=progress if=/dev/zero of=/dev/sda wipe disk
gdisk /dev/sda
o clear gpt table
boot partition

poweroff
Pulling the arch installation medium out of the computer and starting it.
The booting output
:: running early hook [udev] Starting version 248.3-2-arch :: running hook [udev] :: Triggering uevents... :: running hook [keymap] :: Loading keymap...done. :: running hook [encrypt] A password is requires to acces the root volume: Enter passphrase for /dev/mapper/vg1-cryptroot: {inserting passphrase} :: performing fsck on '/dev/mapper/root' :: mounting '/dev/mapper/root' on real root :: running cleanup hook [udev] ERROR: Root device mounted successfully, but /sbin/init does not exist. Bailing out, you are on your own. Good luck. sh: can't access tty; job control turned off [rootfs ]# Obviously I didnt setup cryptswap and crypttmp, yet. Those will be setup with crypttab and fstab. I am just mentioning this, and highly doubt it is part of the problem, because they are just partitions not recognized by anything at the moment, aren't they.
I hope I didn't miss any command or configuration I did - I am typing off videos I watched and from head, because no single video I found had the btrfs, luks, lvm config I went with. Thanks for your time/help and reading this through.

Adding rootflags=subvol=@ to /boot/loader/entries/arch.conf like so
title Arch Linux linux /vmlinuz-linux initrd /initramfs-linux.img options cryptdevice=UUID={/dev/vg1/cryptroot uuid inserted here}:root root=/dev/mapper/root rootflags=subvol=@ rw did the trick.
