The only place I can currently find that people actively advocating this
is the forum (e.g.
http://ubuntuforums.org/showthread.php?t=456662&page=6 ). It's hard to
retrace all the pages I've seen though as this topic has become very
popular and consequently I've looked at a lot of different pages related
to it.

I'm aware of this but those pesky /dev/<blockdev> names have infested
Ubuntu in a deep seated way. The machine I am using at the moment had a
fresh install of Feisty (via the alternate CD) but has a resume device
set to RESUME=/dev/hda6 in /etc/initramfs-tools/conf.d/resume . On the
same machine all the partitions have UUIDs, but the CDROM/DVD device is
still being referred by /dev/hdc (nor is referencing CD/DVD/Floppy disk
drives in this fashion uncommon with fresh Feisty installs). I've
suggested people use the /dev/cdrom symlink in bugs like
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/118188 but I have no idea whether this advice is good or whether it produces unwanted side effects.

Further, /dev/<blockdev> names still have a hold on hddtemp
( https://bugs.launchpad.net/ubuntu/+source/hddtemp/+bug/117621 ) along
with dmcrypt+LUKS
( https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/117979 ) not to mention things like /boot/grub/device.map along with who knows what else. There is also an issue surrounding swap and UUIDs ( https://bugs.launchpad.net/bugs/118199 ).

I've just done some more searching and I neither of the two release
notes for either Edgy ( https://wiki.ubuntu.com/EdgyReleaseNotes ) nor
Feisty ( http://www.ubuntu.com/getubuntu/releasenotes/704 ) mention
that /dev/<blockdev> names should no be used in configuration files.
Contrast this with the latest Fedora release notes
(http://docs.fedoraproject.org/release-notes/f7/en_US/sn-Installer.html#id3152635 ). I mentioned it in my previous mail but I'm going to ask again - is it possible to have a second set of release notes that has similar technical information to the Fedora release notes within it?
