# Yes, we are hardcoding a path here. Yes, it's ugly. However, the program
# will attempt to run this script as root, and I do NOT want to make it try to
# "find" the script and execute the first thing it finds that has the right
# name, that sounds like a security breach waiting to happen. It will only
# execute lubuntu-update-backend from /usr/libexec, and if something malicious
# has gotten into /usr/libexec you're compromised anyway, so not much to worry
# about. Therefore we always, *always* install this script into /usr/libexec/,
# no matter where the rest of the program goes.
