 By default the daemon is watching the directory `/.snapshots`. If the daemon should watch a different directory, it can be edited by passing different arguments to it.
 Arguments are passed to grub-btrfsd via `DAEMON_ARGS` and `SNAPSHOTS`
 variables in the script `/etc/init.d/grub-btrfsd`.
-The variable `SNAPSHOTS` defines the path the daemon will monitor for snapshots.

+After editing, the applicable portion of the file should look like this:

+``` bash
+SNAPSHOTS="/.snapshots" # Snapper in the root directory
+# SNAPSHOTS="/run/timeshift/backup/timeshift-btrfs/snapshots" # Timeshift < v22.06
+
+## Optional arguments to run with the daemon
+# Append options to this like this:
+# DAEMON_ARGS="--syslog --timeshift-auto --verbose"
+# Possible options are:
+# -t, --timeshift-auto  Automatically detect Timeshifts snapshot directory for timeshift >= 22.06
+# -o, --timeshift-old   Look for snapshots in directory of Timeshift <v22.06 (requires --timeshift-auto)
+# -l, --log-file        Specify a logfile to write to
