I'm running Arch Linux with systemd boot. In /boot/loader/entries/arch.conf I currently specify the luks crypto device with a line like this:
options rw cryptdevice=/dev/sda1:ABC root=/dev/mapper/ABC
I know I can also use UUID instead of /dev/sda1. In that case the kernel options line would look like this:
options rw cryptdevice=UUID=1f5cce52-8299-9221-b2fc-19cebc959f51:ABC root=/dev/mapper/ABC
However, can I instead use either a partition label or a volume label or any other kind of label? If so, what is the syntax?
kernel luks dm-crypt systemd-boot

cryptsetup can create a label on a cryptdevice. Look in /dev/disk/by-label to make sure it matches. So
cryptdevice=LABEL=labelname
in the same way as
root=LABEL=ROOT
works for a ROOT labelled root device
