# Script used for running executables with custom labels, as well as custom uid/gid
# Process label is changed by writing to /proc/self/attr/curent
#
# Script expects user id and group id to exist, and be the same.
#
# From adduser manual:
# """By default, each user in Debian GNU/Linux is given a corresponding group
# with the same name. """
#
# Usage: root@desk:~# python notroot.py <uid> <label> <full_path_to_executable> [arguments ..]
# eg: python notroot.py 1000 User::Label /bin/ping -c 3 192.168.1.1
