BTRFS LVM EFI config

[Thackeray, Neil L]

Yes, I do have mkfs.btrfs installed in nfsroot. I did a grep for btrfs on the logs and didn't see anything outside of the configs.

You are right, the mkfs.btrfs call is missing.

BTRFS is supported by setup-storage (disk_config), but I'm not sure if
on a LVM?

Do you have mkfs.btrfs in the nfsroot? Check if this error is in the
logs:
BTRFS tools not found in PATH
