automount usb mass storage
 

Hello peeps,

I've got a debian 4 (etch) system with kde. Every time I stick in a usb flashdrive it auto-mounts and asks if I want to open it or not. I have no problems with it.

However, I want to change the way it mounts so that I can use the uuid of the flash drive to assign it a static mount point (ie: always mount flashdrive with uuid=7586-3937 to /media/flashdrive1). I haven't gotten the chance to see what happens if I insert two flashdrives at once... but I think it would be random which flashdrive would mount where.

My question is: where does all this magic happen? I have no mentions of the flashdrive in my fstab. I've tried putting a line including the uuid and mount point in my fstab which leads to permission problems when I try to mount it. Another thing I find strange is that the current mount point for the flashdrive gets created on the fly when I insert the flashdrive. /media/disk does not exist when the usb flashdrive is not mounted - but it does exist when it is mounted. I always thought the directory had to exist before the usb flashdrive was mounted.

Can anyone point me in the direction of where to find where all this magic happens so I can poke around and try to configure it to my liking?

Thanks

This is one possibility:
plug in stick
"dmesg" look for the device, let's say it's sdc:sdc1
"udevinfo -a -p `udevinfo -q path -n /dev/sdc` | grep serial" #get the serial, for me: ATTRS{serial}=="0602101948231"
add to the top of /etc/udev/rules.d/60-persistent-storage.rules the following line:
BUS=="usb", KERNEL=="sd?1", SYSFS{serial}=="0602101948231", NAME="kingston", SYMLINK="kingston%n"
use any name, I have kingston there
add to /etc/fstab the following line:
/dev/kingston1 /media/kingston vfat noauto,users,exec,noatime,umask=000 0 0
make a dir under media:
drwxrwx--- 2 root users 4096 2008-08-24 13:15 kingston

Plenty more on google for usb and udev.

Edit: You might have to do "/etc/init.d/udev restart" before it works, can't remember.

udevrules dont look in the fstab file
Do a good udev rule and works fine
and remember to add the user to plugdev and messagebus.

bye

No. You can set permissions for mounting in fstab like above, but yes, you could also set them in the rule.

Thank you guys. I found the udev stuff earlier, but I was scared - it looked deep and important. I will read a little about it and give it a try. I didn't know that was where it all happend. Good to know.

Thanks again.

Worked like a charm. Now it always mounts where I want it. Fantastic. Makes it easier to write a backup script or something... haven't really done anything yet. But I'm happy.
