Indeed it would be, but it's not possible yet since the kernel is not
sending the right kind of uevent:

https://www.redhat.com/archives/dm-devel/2006-August/msg00040.html


The dmsetup package should install this rules file and link it at z47:

KERNEL!="dm-*",					GOTO="device_mapper_end"
ACTION!="change",				GOTO="device_mapper_end"

# do not run vol_id if it's a snaphost or dmsetup failed
PROGRAM!="/sbin/dmsetup status -j %M -m %m",	GOTO="device_mapper_end"
RESULT=="|*snapshot*|*error*",			GOTO="device_mapper_end"

IMPORT{program}="vol_id --export $tempnode"

ENV{ID_FS_USAGE}=="filesystem|other|crypto",	ENV{ID_FS_UUID}=="?*", \
	SYMLINK+="disk/by-uuid/$env{ID_FS_UUID}"
ENV{ID_FS_USAGE}=="filesystem|other",		ENV{ID_FS_LABEL_SAFE}=="?*", \
	SYMLINK+="disk/by-label/$env{ID_FS_LABEL_SAFE}"

LABEL="device_mapper_end"
