Date: Sat, 6 Jun 2020 15:40:15 +0200

Hi,

I’ve tried the patches, but `guix system reconfigure` fails(?) with

	building /gnu/store/cy6d2a4b8bcqcjiaz8bm367j7vbdrslc-upgrade-shepherd-services.scm.drv...
	guix system: error: exception caught while executing 'start' on service 'device-mapping-disk3-data':
	error: <>: unbound variable

Relevant part of my config.scm:

	  (mapped-devices
		  (list (mapped-device
				  (source "disk3")
				  (target "disk3-data")
				  (type lvm-device-mapping))))
	  (file-systems (append
					 (list …
							(file-system
							 (device "/dev/mapper/disk3-data")
							 (mount-point "/storage/disk3")
							 (type "ext4")
							 (dependencies mapped-devices))
						   )
					 …))

I’m also curious why sources is a list of VG’s as opposed to a list of device
nodes (i.e. /dev/sdX), like the other mappings. Does `pvscan --cache` not work
here?

Lars
