That was my idea behind it. I often see other programmes use an
environment variable instead of a command-line argument to pass sensitive
information like passwords, presumably because it is better hidden there.
If root or the process owner (here: root) can access it, that's no problem
because root should access it anyway. duplicity for example reads passwords
from an environment variable rather than an argument.
I haven't tried getting the command line of root processes from an
unprivileged user though.
I'll try the other env variable later, so maybe I don't need the patch
