Hey all! 
I'm trying to create a fixed mount point for an usb cardreader.
I've found a script on a raspberry pi forum which does the following:
usb stick is plugged in -> script checks the mount point for data -> script starts copying the files automatically -> script unmounts the stick/partition.
The problem is: The script is using a fixed mountpoint. the author of the script can do that because he is always using the same camera with the same partition name (GOPRO). I want to use that script to copy files from many different cameras and many different manufacturers.
BUT i will always use the same cardreader (which has a unique serial i could use)
Thats the script im referring to:
UDEV rule (50-sdcopy.rules)
# Run Script as a new process when any device is added
KERNEL=="sd[a-z]", SUBSYSTEM=="block", ACTION=="add", RUN+="/bin/su root -c /opt/bin/myfork.sh"
Then the myfork.sh script
#!/bin/bash
date >> myfork.log
setsid /opt/bin/goprosync.sh > setsid.log
This script is necessary (myfork.sh simple runs a new process that is disconnected from the calling script. Otherwise udev would kill long file transfers).
And here the actual copy script.
#!/bin/bash
# If the script detects the existence of both the source and destination disks
# then the contents ot the GOPRO folder is synchronised with files on the BACKUPDISK folder.
# Ensure that the Partition Label's on all your devices are set accordingly.
## Make sure the script isn't already running from a previous disk connection

What i want to do:
The card reader should be always mounted at the same mount point (/media/cardreader).
How could i do that?
Add something to the 50.sdcopy.rules? Add something to the script?
Thanks in advance!!!
Kind regards
