Was booting 3 of out 4 boots. I suspect a timing issue because I've got 5 drives hanging off an LSI controller in pass-through mode.
So I've been hacking away and now managed to kill booting entirely.
Each boot now goes:
Starting version 245.3-2-arch
ERROR: device 'UUID=f07b3ab8-blah blah (copying from photo)' not found. Skipping fsck.
mount: /new_root: can't find UUID=f07b3ab8-whatever.
You are now being dropped into an emergency shell.
If I then immediately dmesg | grep f07b3ab8-fulluid
[ 0.00000] Command line: BOOT_IMAGE=/boot/vmlinuz-linux root=UUID=f07b3ab8-yep rw loglevel=3 quiet root=f07b3ab8-yes-again
[ 0.342833] Kernel command line: [snip - same as commandline]
[ 11.497354] BTRFS: device fsid f07b3ab8-blahblah devid 1 transid 1115 /dev/sdf2 scanned by systemd-udevd (392)
I'm using grub.
If I manually mount - e.g. mkdir /tmp/f && mount /dev/sdf2 /tmp/f then I've got access to the root fs.
I can't mount /dev/sdf1 - unknown filesystem type 'vfat'.
I can boot from USB ISO image and mount /mnt and /mnt/boot, mkinitcpio -p linux etc to no avail.
I've even gone though the basics of setting up again - full blown pacman -S linux grub efibootmgr, grub-install, grub-mkconfig -o /boot/grub/grub.cfg
After 4 hours I'm stepping away, defeated. I've googled, I've read the wiki, and I've already got 4 successful installs (1 physical, 3 VMs in KVM).
Happy to post copies of /etc/fstab etc with the full non-typed UUID, if anyone can tell me where to start.

Hmm... scratch that. Can't be a timing issue otherwise the initial arch boot wouldn't have started.
<continued head thumping>
Booting from the iso image:
sdf2 is the root partition, sdf1 is the boot partition.

Unbroken it - somehow I'd accidentally mounted the EFI image on /boot rather than /boot/efi.
So now I'm back to failing to boot as per the original message - for some reason some of the time the host just won't find the disk, though since it's just a partition on the same disk I can't understand why.
Manually powercycling and it'll either drop back into the failed shell, or boot properly, depending on it's mood.
