There is no need to include the display number in the file name because `systemd` automatically creates the appropriately named instance in memory on demand, replacing `'%i'` in the service file by the display number. For a single user it is not necessary to rename the file. For multiple users, a uniquely named service file for each user is required, for example, by adding the user name to the file name in some way. See xref:TigerVNC.adoc#configuring-vncserver-2users[Configuring VNC Server for Two Users] for details.
