At least on my system (udev), they certainly do exist, for example: % ls -l /dev/mapper/ravenclaw-root lrwxrwxrwx 1 root root 7 Jan 20 09:01 /dev/mapper/ravenclaw-root -> ../dm-0 % ls -l /dev/ravenclaw/root lrwxrwxrwx 1 root root 7 Jan 20 09:01 /dev/ravenclaw/root -> ../dm-0 % ls -l /dev/dm-0 brw-rw---T 1 root disk 253, 0 Jan 20 09:01 /dev/dm-0 So the dm-n devices all do exist, and one can work out which logical volume each represent by looking at the symlinks.

Exactly. And note that actually, these are dm devices, which
usually appear as /dev/dm-N (cf. multipath devices created by
multipathd - they symlink from /dev/mapper/name to /dev/dm-N).
And this is an interesting place.
The "problem" is that kernel does not know what /dev/mapper
is, or what does /dev/r/usr thing mean. It knows these by
their canonical (and meaningless) dm-N names, like this:
[6.887981] EXT4-fs (dm-0): mounted filesystem with ordered data mode. Opts:
(null)
[6.917555] EXT4-fs (dm-1): mounted filesystem with ordered data mode. Opts:
usrquota
Go figure which is dm-0 and which is dm-1 (lvm is here)!
There are references to these dm-N names in /proc/partitions
and in /sys and elsewhere, too.
I consider this a bug, a quite serious one at it: there's
no device node which corresponds to kernel names! So it is
impossible to get, eg, device usage statistics for a
particular volume, or map i/o error to particular dvice and
so on. This is wrong.
But this is a different problem entirely.
My point is that actually, _both_ /dev/mapper/r-usr and
/dev/r/usr are wrong! But at least they - hopefully -
lead to the actual device, unlike kernel messages I
mentioned above which leads to nothing due to /dev/dm-0
non-existing.
> What result does "LABEL=..." get?
It is exactly the same as with UUID=. For both of these,
util-linux mount will canonicalize the name to final
device (like /dev/sda1 or /dev/dm-0 or /dev/mapper/r-usr
as in your case), be it LABEL= or /dev/disk/by-label/LABEL.
While neither busybox nor klibc will do that. Besides,
klibc does not support LABEL or UUID, in busybox it is
optional (compile-time), and it will do its own resolution
of LABEL/UUID, without using /dev/disk/by-*/.
In initramfs, both are handled the same way
(omiting some details for brevity):
initramfs:init:
case $ROOT in
LABEL=*)
ROOT="${ROOT#LABEL=}"
ROOT="/dev/disk/by-label/${ROOT}"
;;
UUID=*)
ROOT="/dev/disk/by-uuid/${ROOT#UUID=}"
;;
So this gives /dev/disk/... arg to mount, be it from
busybox or klibc, and neither calls realpath(3).

Any update on why the root filesystem is listed by UUID? Is that a
problem of busybox mount reporting the long device name to the kernel
why real mount uses the short one?

As a side note: With LVM you get entries like:
/dev/mapper/r-usr 7224824 6392404 465460 94% /usr
I would much rather have:
/dev/r/usr 7224824 6392404 465460 94% /usr
But I guess the solution for this would be to have udev make /dev/r/usr
the real device and /dev/mapper/r-usr a symlink.

Or add readlink into initramfs-tools, for that matter.
But it is still not clear if it is a bug or not :)

It is due to busybox mount, which does not perform any canonicalizing
of the device argument but passes it as-is to the kernel. On the
contrary, mount from util-linux resolves the symlink if given as
the device name.
And initramfs does this:
init: UUID=*)
init: ROOT="/dev/disk/by-uuid/${ROOT#UUID=}"
whichis later passed to busybox's mount, which happily passes
this /dev/disk/... stuff to kernel, which in turn happily
shows it in /proc/mounts.
It looks like mount from klibc does not do any canonicalisation
too, only util-linux mount does.

It is not clear - to me anyway - if it is a bug or not. Yes it
definitely makes df and other utils output difficult to read.
And yes it is kinda trivial to add a call to realpath(3) to
busybox (or equivalent).

Regarding the issue with booting, this was due to a problem with startpar and should now be fixed (#652097). Fixed packages are at http://people.debian.org/~rleigh/sysvinit/ and it will hit experimental shortly. I'd be grateful to know if this fixes the issue for you as well. Thanks, Roger -- .''`.

Actually, /proc/self/mounts would be preserved; any symlink into /proc is considered acceptable. Anything else would be changed. -- .''`.

It does--it will switch to /proc/mounts unless /etc/mtab is already a symlink to /proc/mounts. It will therefore correct any symlinks which point to other places as well as the usual case of it being a file. Regards, Roger -- .''`.

You probably want to handle the case where /etc/mtab is a symlink to /proc/self/mounts as well, since it's equivalent, and I know some people (read: at least me) have already made that change. -- brian m. carlson / brian with sandals: Houston, Texas, US +1 832 623 2791 | http://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: RSA v4 4096b: 88AC E9B2 9196 305B A994 7552 F1BA 225C 0223 B187 signature.asc Description: Digital signature
Switching /etc/mtab to /proc/mounts and removing /lib/init/rw
Hi folks, The above have been mentioned a few times during the course of the year, but we're now at the point where all the prerequisites have been satisfied, and there are no blockers present to proceed. I've put a proposed set of packages at http://people.debian.org/~rleigh/sysvinit/ which I plan to upload to experimental soon, and then to unstable following some testing. If you have a few minutes to spare, some testing of the packages would be appreciated, so make sure there are no corner cases we've missed. Upgrading initscripts should result in /etc/mtab being switched to a symlink at the next reboot. /lib/init/rw will also no longer mount a tmpfs on reboot, though the directory itself will need to remain until wheezy+1, due to the upgrade ordering--packages migrate after initscripts has run its postinst, requiring its continued presence. I'd be grateful for any feedback. Thanks, Roger -- .''`.
