# Name: gparted
# Purpose: Perform appropriate startup of GParted executable gpartedbin.
#
# The purpose of these startup methods is to prevent
# devices from being automounted, and to ensure only one
# instance of GParted is running. File system problems can
# occur if devices are mounted prior to the completion of
# GParted's operations, or if multiple partition editing
# tools are in use concurrently.
