Don't know what you've been reading. :-(

Now in *Ubuntu "vol_id" is used most of the time:

UUID=ce99adfa-da77-4199-8e82-13579f10daa4 /home ext3 defaults 0 2
to get this string:
type as root in a shell: 'vol_id -u /dev/XYX' and start the line with
'UUID='

I used various Gnu/Linux distros myself too, and I haven't
really bothered to read up in the changes and why the
*Ubuntu developers use the above scheme.

And yes I too had to unlearn, from mounting in /mount to
use /media instead, but I don't really understand your
misgivings about having to use /media instead of /mnt. As
long as I can access the files, I really don't care that
much.

No Microsoft, Apple, Intel, Novell, Trend Micro, nor Ford products were used in the preparation or transmission of this message.

The EULA sounds like it was written by a team of lawyers who want to tell me what I can't do. The GPL sounds like it was written by a human being, who wants me to know what I can do.

Hi Dragomir,
Thanks for your comments.
What have I been reading? Anything and everything I can get my hands on
these past few days re booting, partitions and mounts!
As always on the net there is a lot of info but much of it unclear, some
outdated and also some clearly wrong.

For example I've seen 3 things continually repeated:
1. don't ever ever make a directory immediately under /
2. you can put mount points anywhere you like. It's all the same.
3. put mounts points of fixed drives under /mnt and for removables put under
/media.
?*!

Yes I have got it working now in Ubuntu and without invoking UUIDs (I did
read why they had changed to this and it makes sense but I also like using
volume IDs) but :
4. it didn't work the way all the articles I read about mounting said it
would.
5. there is obviously some difference between mounting under/mnt and under
/media in Ubuntu. eg automatically putting icons on the desktop and the way
it interacts with Nautilus .
My curiosity and desire to learn says I'd like to know more why the change
and what are its consequences.
Hopefully someone must know out there.
Cheers.
Dave

The reasons are simple. When using potentially non-persistent drive
connections, the sdX (or hdX) designation can easily change. USB is
an obvious one, but also affected are systems connected to a SAN. For
instance, a few years ago I was called to work on a redhat server that
wouldn't boot. The problem ended up being that the SAN connection
wasn't working. When the SAN was working right, the SAN took the low
designations (sda, sdb - sdf). The /boot partition on the local RAID
adapter was pushed out to sdg. Without the SAN, the local /boot was
now sda.

This could be addressed through labels as well, but they need to be
manually assigned, whereas the UUID is automatic and (in theory)
unique.

I still use /mnt for most things. I don't need (or even want) icons
for my mounts showing up on the desktop. I know where they are, so
why clutter the desktop?

Just mount them under /media if that is your goal. Seems simple
enough...

Thanks for the link, I guess I should have read up on it a
bit earlier... :-) I'm using sometimes up to three different
usb-sticks, external HDD's and assigning them the UUID in
/etc/fstab allows me to mount them on the same mount-point,
every time I connect them. No matter the order.

To the other Poster, I used for years a light-wight
file-manager called "worker" and I didn't get to use
nautilus, also I like the old-way of mounting/unmounting the
devices manually.....
