Nautilus shortcut, unmounted volumes

[pkcarlisle-dot-com]

Here's what I run:

CentOS 6, 64-bit

Here's what I have:

Volume x. My archives volume. By default, not mounted. If I select volume x I need the admin password to mount it. By default not accessed on-the-fly. Only accessed for archiving the occasional item which really needs immediate backup. All of the above is uh-huh-oh-yeah, the way I like it. I am not looking to have x mounted as a rule, or to change its behavior in any way.

What I want:

To add a desktop or taskbar shortcut to exactly the same thing that happens above, specifically, when I click the taskbar icon, to be prompted for the admin password prior to mounting x OR to bring up x in nautilus if x is already mounted for some reason (normally it won't be mounted already).

What I see:

When I mount x through nautilus, I get the prompt for the admin password, enter it, and get x mounted at /media/x. Perfect. Just what I want.

But

When I try to create a custom launcher with the command nautilus /media/x if x is not mounted I get a 'could not find /media/x/ error box. Well, yeah, I /know/ it can't find /media/x/, it's not mounted yet.

What I would like:

To have my copy/custom shortcut offer the same prompt for a password to mount /media/x/ that I get if I click the volume in nautilus.

Is this possible? I'm guessing so, since either way nautilus is the file manager. Any ideas?

Thanks a lot!

It feels a bit like a script kiddie (I am more partial to Python, bash scripting is not my strong suit), but I found a solution to the above.

- Zenmap has a script to load in user or in su mode. The su script requires an admin password to proceed.
- I adapted that script for my shortcut.
- Save the script as a script then point a custom launcher to the script.
- If there is anything grossly wrong/insecure/etc. with this approach, please post a response.
