Using /etc/cgd/ROOT.<suffix> has the advantage that the cgd will configure if the root device changes name, thus upholding POLA. E.g. moving disks from a controller that attaches sd(4)s to one that attaches ld(4)s. I believe you can see that when dd'ing an image from SDcard to MMC on Pinebook. It seems to me that similar behaviour for NAME=label would be more useful too. dk(4) attachments move around in practice. --chris
