I'm having trouble getting btrfs to work with a LVM EFI partition scheme. The 
following is the closest thing I have to working. I'm currently getting the 
error: /sbin/blkid -c /dev/null -s UUID -o value /dev/vg1/home had exit code 2

My disk_config:
# entire disk with LVM, separate /home
disk_config disk1 disklabel:gpt fstabkey:uuid align-at:1M

p=efi     /boot/efi   512M     vfat   rw
p=boot    /boot        500      ext4   rw,noatime
p=system  -           4G-      -      -

disk_config lvm

vg vg1  disk1.3
#vg vg1 disk1.lvm_pv

#vg1-root   /        3G-50G   btrfs   
noatime,ssd,space_cache=v2,compress=zstd:3,rw
#vg1-swap   swap     200-4G    swap    sw
#vg1-home   /home    600-      btrfs   
noatime,ssd,space_cache=v2,compress=zstd:3,nosuid,nodev,rw

vg1-root  /      3G-50G  btrfs  
defaults,noatime,ssd,space_cache=v2,compress=zstd:3,rw,label=rootfs
vg1-home  /home  600-    btrfs  
defaults,noatime,ssd,space_cache=v2,compress=zstd:3,nosuid,nodev,rw,label=homefs

This is your disk_config file:
# GPT layout
# entire disk with LVM, separate /home
disk_config disk1 disklabel:gpt fstabkey:uuid align-at:1M

p=efi     /boot/efi   512M     vfat   rw
p=boot    /boot        500      ext4   rw,noatime
p=system  -           4G-      -      -

disk_config lvm

vg vg1  disk1.3
#vg vg1 disk1.lvm_pv

vg1-root  /      3G-50G  btrfs
