I have a systemd user unit that is activated and has a timer to run every day at a certain time. The problem I am having is that if the server is rebooted (and I don't know when that might happen) the service stops running and then I eventually notice the process has not run for a while and I login... It then starts right when I login and begins to run.
How can I make it so that it automatically resumes the timer/service when the server is rebooted so I can avoid having random outages of my process?

# systemd does not support symlinks across partitions, copy service and timer to user dir
# enable timer which calls service by the same name
