I tried to find out what the motivation is for that, and I came across a posting from you where you state: "The reason for doing so is that creating nodes root /dev directory is considered to be the "standard way"." I'm currently on Ubuntu 9.04 and I don't have any /dev/dm-* devices, only /dev/mapper/* (eg. "raid5-root"), which have much more meaning for humans. The system works, so there seems to be no actual need for /dev/dm-* devices. Maybe it's time to loosen the "standard way". I have the strong feeling that we're going backwards with respect to usability if eg. df reports meaningless /dev/dm-* names, so the human has to look up what this actually means. Yours, Uwe
