+# Arch Linux:
+# The user and group must be the same. Change all 4 at once. Don't pick a system defined user.
+# If you change the user and group names after installation, you should:
+# 1) userdel 'olduser' # if it's not being used for something else
+# 2) groupdel 'olduser' # if it's not being used for something else
+# 3) rm -rf '/.olduser' # if there's nothing in here of importance
+# 4) newrelic-sysmond.inst install # to create new user, group, and to chown folders
+
+# If you uninstall another New Relic package and find that the user and group have disappeared
+# simply run: newrelic-sysmond.inst install
+# or just upgrade the package
