Is it possible to mount different usbsticks automatically on insertion to different mountpoints?
I'd like to have my mp3-player-usb-stick at /mnt/mp3playerstick, another stick at /mnt/128mbstick and the big one to /mnt/512mbstick.
Do I need udev for this, or can it be done with devfs? |

With devfs check this topic: https://forums.gentoo.org/viewtopic.php?t=118474
With udev it is quite simple.
Just add a line like the following to udev.rules:
| Code: |
BUS="scsi", KERNEL="sd*", SYSFS{model}=" USB Drive", NAME="%k", SYMLINK="memstick" |
The "*" in "sd*" is correct.
The model name can be found in /sys/block/sdx/device/model. |

| so that udev bits you pasted would link the /dev/sdxy where a usb-stick with the model name " USB Drive" is connected, to /dev/memstick, did I understand that right? what happens if I have two usbsticks that have the same model name? |

You can do device matching through a number of mechanisms, not just the model name. For example, you can match devices based on their serial number, which, I imagine, would solve your problem. To wit: | Code: | | BUS="scsi", KERNEL="sd*", SYSFS{serial}="<device serial number here>", NAME="%k", SYMLINK="memstick" |
What if you somehow have two devices with the same serial? (What are the odds there?) You can use any number of keys to specify a device. For example, you could add SYSFS{model}="xxxx" to the above line to match both the serial number and model.
A good reference is at Writing udev rules. I believe there is a link to a script that allows you to get all the SYSFS info about your devices at Decibel's UDEV Setup (look for udevread.py.)

udevinfo, which comes with udev, will give you the info.
Also, for auto mounting, do a search for ivman |
