I use mc from a konsole to do my file browsing. I'm quite comfortable

happening?

I'd actually prefer a root command line solution that will
make it impossible for kde to turn automounting back on.

In case it matters, I boot to runlevel 3 and start kde via startx as
needed.


I ran into the exact same thing last night. A file system marked
"noauto" was mounted at boot time. I had to comment out the line
in /etc/fstab and hack around the problem (put something in rc.local)
but it's a royal hack, not a solution.

The culprit is gnome or kde... for kde, I don't know, but for gnome you
have a System>Preferences>Removable medias (something like that) where
you can choose what you want.

Anyway there is some problem there: as cd/dvd devices are no more
mentionned in fstab, I think that if you don't use auto-mount, you will
be unable to mount your cd/dvd if you are not root....

This is boring: same happens if you want to format a cd/dvd/usb-key...
whatever, you cannot unmount them to perform the operation if you are
not root...

The problem is definitely not gnome or kde. The mount happens at boot
time, right after udev. Also, the line I had in fstab was mounting a
usb 250GB external hard drive. No CD or DVD drives involved.

I see the LVM find my logical volume (VolGrp00/LogVol00, or something
similar), I see udev "start" (I can't remember the line in the
start-up--I think it says "starting udev"), then I see an error saying
the drive with a specific label can't be found. I can then provide the
root password to get in and fix the problem. The drive with the label
that can't be found is marked "noauto" in fstab. I've had it marked
"auto" and everthing's worked for the past three months, but suddenly
last night it stopped working so I tried "noauto" to skip the mount at
boot time. The disk has the same, correct label--I checked. I switched
back to "auto" and just commented out the whole line in fstab, rebooted
the system to run level 3, uncommented the line in fstab and ran "mount
-a" with no errors, so I know it's not the disk label. I suspect it's
something with the disk device (/dev/sdb1, I believe) not being found.
But why "noauto" doesn't prevent the device from being mounted at boot
time is a mystery.

As I type this an idea to test just occurred to me, so I'll try it
tonight when I get back to my office.

I don't this it applies here. HAL isn't involved. This is right after
udev starts, right at the start of the boot process. HAL starts much
later. At least that's my understanding based on when I see service
start (I could be way off, though).

Also, from the page you point to:
On a similar note, Fedora 8 changed the way hal is configured so
that all fixed disk partitions get mounted by default (even
partitions you deliberately left out of the /etc/fstab file
because you didn't want people fooling with them).

With the line commented out of my fstab file the usb hard drive isn't
mounted at all. Ever. However, I'll re-verify that this evening.
