OK, looks like there's a bug in some versions of findmnt from util-linux (although Debian and Ubuntu place the utility in the mount package). This bug prevents the full tree output from displaying.

http://thread.gmane.org/gmane.linux....557/focus=8558

This was fixed in util-linux version 2.25. From my Utopic box:

steve@t520:~$ [B]findmnt -V[/B]
findmnt from util-linux 2.25.1

steve@t520:~$ [B]apt-cache policy util-linux[/B]

Note that prior versions of findmnt even lack the -V option.

Yes, I too get the entire hierarchy with no parameters. I think we're agreed on the weirdness of this bm2lts system.

[SteveRiley]

On my system, findmnt displays the entire mount hierarchy with and without the -A option. On kdeuser's machine, the command displays only a single line. That's very weird.

[SecretCode]

Trusty right now, Precise earlier. Still no -A option here. And I think kdeuser's custom build is based on Trusty, so that would explain why the same error message appears there.

reel@BM2LTSR66RBin:/media/hd/home/reel$ findmnt -A
findmnt: invalid option -- 'A'

Wow, whatever version of Ubuntu this distro uses is weird... -A is normally allowed.

Not on my Kubuntu 12.04 (I get the same error). Does this require a newer version of findmnt?

You know, you're right... I'm so wrapped around this tmpfs thing and the totally weird outputs from fuser that I overlooked that.

I'm not sure there's much value in trying to deconstruct this system any longer. I'm fairly confident in stating that trying to get Kubuntu running on it will be a lost cause, because so much of the underlying configuration deviates from what Kubuntu expects. Kubuntu expects a mostly standard Ubuntu base. This distro is definitely not that.

I've said that on this thread -> https://www.kubuntuforums.net/showth...l=1#post366559

If kdeuser wasn't stubborn he's have had kubuntu installed on his multimedia machine installed all the dvb stuff and he could have watched his video/tv on the device by now.

Then I am flummoxed. Note that the access type is simply MOUNT. No process appears to have open files. The umount should work.

There seems to be several other filesystems mounted under media, you can't unmount /media from under (or rather over) them...the user's $HOME seems to be there too <-- "reel@BM2LTSR66RBin:/media/hd/home/reel$"

This distro you're running is very nonstandard.

It looks like an embedded installation (or semi-embedded), some of them have quite complex set-ups (sometimes for good reasons, other times not)...it can be quite a tedious task to figure one out without documentation, especially remotely via a forum).

@SteveRiley,

My bad on the fuser. It should be sudo fuser -vm /media
