In order to prevent potential corruption of newly created file systems, when available use udisks2-inhibit with gpartedbin execution to prevent automounting. Original report: Xubuntu install fail due partition auto mount defeats Gparted https://bugs.launchpad.net/ubuntu/+source/thunar/+bug/1078445 Some GNU/Linux distributions use the udisks2 "udisksd" daemon and have udisks2-inhibit at a known location. The known location is not in the default PATH environment variable. One known distribution that matches this criteria is xubuntu 14.04. Interestingly neither kubuntu 14.04 nor ubuntu 14.04 appear to have the udisks2 "udisksd" daemon running and do not suffer from this specific automounting problem. Bug 745349 - gparted wrapper script needs updated for udisks2

# 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.
