Actually I was recently wondering a bit about the unmounting part,
especially with USB sticks. I do have udev rules, taken from the wiki,
in place that handle automatic mounting. There's also a unmounting part,
which afair removes created dirs, but I guess this is only called after
the usb drive is removed. It did happen more than once to me that a file
transfer seemed to be complete, but when I just removed the drive, the
data was gone. Is there a way to provide automatic safe removal? Manual
unmounting is a bit of a PITA, as you need to have a terminal ready,
guess sdN and type a line, where the device guessing part is the most
problematic. I tend to use /dev/sdN to make sure that I remove the
device from all mount points. Thanks for any advice.
