+# Configuration for netdata-updater.sh script.
+#
+# When run non-interactively, the updater script will delay some
+# random number of seconds up to NETDATA_UPDATER_JITTER before
+# actually running the update. The default is 3600 (one
+# hour). Most users should not need to change this.
+#NETDATA_UPDATER_JITTER="3600"
+
+# On systems using our native packages, the updater will by default
+# attempt to install optional plugin packages that would be installed by
+# default on clean installs if those packages are supported on the system.
+#
+# This behavior can be disabled on a per-package basis using the below
+# variables. Setting the variable to a value other than 0 will disable
+# the corresponding package (note that you still need to remove the package
+# yourself if you don0t want it, this just controls whether the updater
+# will try to ensure it’s installed or not).
+#
+# NETDATA_NO_SYSTEMD_JOURNAL controls the `netdata-plugin-systemd-journal`
+# package, which provides the systemd journal plugin for Netdata.
+#NETDATA_NO_SYSTEMD_JOURNAL="0"
