Just for curiosity, where the heck did you find all this? I'm so happy
now :-)

Perfect! This SHOULD be on FC2 - Would make every camera owner's life
easier, specially for those people coming from windoze world.

It does not work THAT perfectly though (just discovered while writing
this) - as camera is mounted as root, I cannot delete directly from
nautilus (or even use camera as a memory stick, which sometimes I do).

Maybe because no one did this for fedora before ;-)

This is just great - but using it with root permissions is not good.
Maybe we can improve this, setting the camera directory to the logged
user.
