# Simple postinst script for guacd which creates a "guacd" user and group
# and sets the permissions and ownership of /var/run/guacd (the location
# of the guacd.pid file) and /usr/share/guacd (the home directory of the
# guacd user).
#
# Exit on errors
set -e

# Convenience function for error conditions.
