Move calling of the privilege escalation program which allows a normal user to run GParted as root from the desktop file into the gparted wrapper script. This is in preparation for further changes needed to grant root access to the X11 display under Wayland. Don't introduce yet another script so that there aren't two different names to run GParted by for normal users and root. Using the same gparted name but placing two different scripts at /usr/bin/gparted and /usr/sbin/gparted is not possible because on Arch Linux /usr/sbin is a symbolic link to /usr/bin. Frequently asked questions, Does Arch follow the FHS? https://wiki.archlinux.org/index.php/Frequently_asked_questions#Does_Arch_follow_the_FHS.3F "Arch Linux follows the file system hierarchy for operating systems using the systemd service manager. See file-hierarchy(7) for an explanation of each directory along with their designations. In particular, /bin, /sbin, and /usr/sbin are symbolic links to /usr/bin, and /lib (and /lib64 if applicable) are symbolic links to /usr/lib". Bug 776437 - GParted fails to run as root under Wayland

# 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.
