Bug#980782: Acknowledgement (os-prober: linux-boot-prober returning "root=/dev/dm-X" line instead of expected "root=UUID=[UUID128])

Just adding, this isn't only a feature request but results in non-bootable systems. If one of the os-probe'd systems e.g. is also a Debian, it will drop into an initramfs due to not finding the root device. This is due to - within the initramfs - the VGs as part of the the LVM system only get activated by certain naming schemes ("/usr/share/initramfs-tools/scripts/local-top/lvm2"). It tries ti figure out whether the rootfs resides on a LVM and if it thinks it doesn't, the respective VG won't be activated, resulting in the passed /dev/dm-X block device not being available.
