Re: [libvirt] [PATCH 1/1] RFC: Canonicalize block device paths

There are many naming conventions for partitions associated with a block device. Some of the major ones are: /dev/foo -> /dev/foo1 /dev/foo1 -> /dev/foo1p1 /dev/mapper/foo -> /dev/mapper/foop1 /dev/disk/by-path/foo -> /dev/disk/by-path/foo-part1 The universe of possible conventions isn't clear. Rather than trying to understand all possible conventions, this patch divides devices into two groups, device mapper devices and everything else. Device mapper devices seem always to follow the convention of device -> devicep1; everything else is canonicalized.
