#158300 — How to disable automatic mounting of CDROM?

I'm trying to troubleshoot a problem.
That Jessie (and IIRC Squeeze) automatically mount the cdrom 
drive every time the drawer is closed is a nuisance requiring to 
manually run umount before I can proceed.

/etc/fstab has noauto under options.

Where else should I look.
I would prefer to disable on a per session basis.
Total disabling is acceptable.

TIA

Probably nothing to do with your problem. From fstab(5)

  noauto do not mount when "mount -a" is given (e.g., at boot time)

Automounting is usually handled by the file manager of whatever DE you
are using.

I'm using Debian 8.0 with Mate as DE. There have been no updates 
installed as internet is not physically available to that machine.

I went to
Applications->System Tools->Caja then to
Edit->Preferences which displayed "File Management Preferences"
chose Media
   selected "Never prompt or start program on media insertion"
   deselected "Browse media when inserted"

It still mounts everything :<

Anything else?

I have a similar experience when plugging in an external USB drive.  I
wish to mount each of several drives at a particular mount point which is
unique to the drive, and not at the next available generic mount point
"/dev/usb..."  And the fact that I have connected a USB drive does not
mean that I wish to mount it.

Updates wouldn't matter because they would not (or should not) alter
such a fundamental process.

Very useful. I think the deselection just stops the CD's contents being
displayed when the CD tray is closed and doesn't affect automounting.

> It still mounts everything :<

I see what you mean.

Try

  gsettings set org.mate.media-handling automount false

"apparently" works
*NOTE BENE* the quotation marks
I ran one DVD
am now running a second

HOWEVER I suspect I've made system wide changes without being 
asked for root permission

*ALSO* it affected BOTH flash drives and CDs

http://manpages.debian.org/cgi-bin/man.cgi?query=gsettings+&apropos=0&sektion=0&manpath=Debian+8+jessie&format=html&locale=en
*NOT* informative

It also does not address pre-systemd

Successfully, we expect.

Policykit will take care of privileges. Nothing to worry about.

Indeed. Is is worth digging into udisks and udev to handle CDs and USB
differently when a left or right click of the mouse does mounting so
quickly?

Nothing to fret about if the easier route is taken:

   System Tools/dconf Editor/org/mate/desktop/media-handling

> It also does not address pre-systemd

I don't follow that.

I'll have to go back and redo from scratch. Just spent a week in 
bed with stomach bug. Don't recall some of the side issues I was 
dealing with.

Hadn't done any previous reading on Policykit. It may address the 
one thing I've found most annoying while trying to move to Linux. 
Users [*PLURAL*] and Groups [*PLURAL*] may make sense in a 
universe of mainframes. Not so much in a setting where only one 
individual has access. I have one machine that has no network 
access whatsoever (let alone internet) - going to lengths to 
protect it from external "threats" can become ludicrous.

Quite possibly. Remember the "P" in PC stands for Personal. YMMV ;)

Front ends are nice, but I want to understand what's under the hood.

I had had the impression that D-bus was inherently part of systemd.
Just had an interesting read through 
https://en.wikipedia.org/wiki/D-Bus and 
http://www.freedesktop.org/wiki/Software/dbus/ [even mentions a 
Windows port ;].

It makes sense in lots of situations, real life ones for schools, colleges, 
workplaces, families, single users attached to the Internet.  You can always 
achieve what you seem to want by always running as root.  So LInux can do 
what you want fine.  Let it also do what others want/need.

I don't always wish to "swat flies with 100mm cannon".
Or as old saying cautions "When all you have is a hammer, 
everything looks like a nail."

Then stop moaning.  Linux is a multi-user operating system.  It always has 
been.  Why should it change totally to suit you?  And anyway, root access is 
what you are saying you want.  So why not use it?  What disadvantages would 
it have in your scenario?  You want "everyone" to be able to do everything.

You missed my point. I had said:
"Hadn't done any previous reading on Policykit. It may address 
the one thing I've found most annoying while trying to move to 
Linux."

Obviously stating that Debian apparently had a solution for my 
percieved problem.
