automount mmcblk devices

I put my camera SD/HC card into my laptop (running Debian/testing) and it didn't mount. Usually I would just run the mount command to get it going:

    dmesg | tail
    mount /dev/mmcblk0p1 /mnt

That unfortunately has some annoyances and I decided to solve this finally.

First I installed usbmount:

    apt-get install usbmount

This is just a simple package that allows you to control how attachable devices are mounted on your system. You can control UID/GID ownership, filesystem flags, etc.

Next I edited the /lib/udev/rules.d/usbmount.rules config file, adding the following two lines at the bottom of the file:

    KERNEL=="mmcblk*", DRIVERS=="mmc_block", ACTION=="add",    RUN+="/usr/share/usbmount/usbmount add"
    KERNEL=="mmcblk*", SUBSYSTEMS=="mmc",    ACTION=="add",    RUN+="/usr/share/usbmount/usbmount add"
    KERNEL=="mmcblk*",                       ACTION=="remove", RUN+="/usr/share/usbmount/usbmount remove" 

And then I inserted my SD/HC card, and my /dev/mmcblk0p1 was automatically mounted under /media/usb0.
