Details.

Say you want to mount a usb stick and give it the
label greener.

If needed:
  sudo apt-get install pmount

Do
  lsblk
Plug the usb stick in and do
  lsblk
again.

Note the new device and its partition.
Let's say the usb stick shows up as
  /dev/sdh
and its single partition shows up as
  /dev/sdh1

Do
  pmount /dev/sdh1 greener

Find it at a new dir:
  /media/greener

If you're pat, it will have perms and owner
  rwx --- ---    pat:pat

Do your work.

Do
  sync
for safety?

Do
  pumount /dev/sdh1
to unmount it.

The directory
  greener
will disapper.

Pull out the usb stick.
