Hello,

I'm playing with my new SD Flash reader. Hald is off. So, I figure the proper place to mount flash cards would be /mnt/memory or /media/memory.

udev makes the SD reader node (sda1) perms: root plugdev 660.
Yet, everything in /mnt and /media is root root 755.

So I cannot write to it as user if I mount it there.

My questions are:

What is the logic behind making everything in /mnt and /media root root 755?
Shouldn't some of them, e.g. memory, be: root plugdev 660?

What is the intended manual mount point for Flash cards in Slackware?

Yes, I know how to change perms. I am just wondering what the logic is behind the default settings.

Thanks!

Users cannot use the mount command.

The logic is that Slackware as supplied is a secure setup. It is the responsibility of the system administrator to assign privileges to users.

The point being .. you could still mount to your home dir .. just do a mkdir and mount ... (if you are in plugdev. .. what is mounted in /mnt or /media is decided by the administrator.

That is what I'm trying to understand. As admin, why would I mount something there if no one can use it? The device nodes are set up so I can easily add users via plugdev. Why then require admin the additional step of changing perms in /mnt or /media? Doesn't HAL mount flash devices for users to /media? Does HAL change /media/MOUNT_POINT perms on the fly?

Perhaps it would be better if I explain what I'm trying to do. As sys admin, if I want to set up my system to mount flash cards with user access, without using HAL, would either /mnt or /media be the logical/expected mount point? If yes, I am then expected (as sys admin) to also change perms and group for said mount point?

It just appears to me that Slackware is all set up for me (as admin) to easily add users via the plugdev group, id est. dev nodes and dev symlinks are pre-configured for it, then stumbles at the intended mount point? What am I missing?

Yes, it's not difficult to change perms. I'm just trying to learn proper/intended Slackware sys admin.

Thanks

There's no need to change ownership or permissions of the mount point (that's required for fuse stuff, but this is not fuse-related).

i said admin decides what is mounted there and he can also decide who gets perms to read/write to it . I never said no one can read anything mounted in /mnt /media

HAL basically runs at extended priveleges (root level priveleges). To get those priveleges HAL needs to be started as root ... HAL is like the admin allowing you to mount drives thats all.

in the wiki , shouldn't it be fmask=113 ? Only then did I get rw-rw-r-- for files...

Yep - good catch. Fixed on the page; thanks!

@Stoker: are you telling us that you plug a flash drive in, and you see it auto-mounted root-root?

No, I'm not using HAL (manual mounting).

The problem was my ignorance of file permissions and vfat. rworkman nailed it.

Thank you very much Mr. Workman (and all the other replies too). I have much to learn, but I'm getting there.
