Sometimes it's good to have a vps be the central location for Synthing. Here is how to do it on OpenBSD.

1. Install Syncthing pkg_add syncthing
2. Enable Syncthing rcctl enable syncthing
3. Update Daemon flag vi /etc/rc.d/syncthing, add -home=/var/syncthing
4. Run Syncthing once to create initial files: /etc/rc.d/syncthing start
5. Stop Syncthing after a few minutes: /etc/rc.d/syncthing stop
6. Update login.conf: vi /etc/login.conf; add syncthing:\ :openfiles-max=60000:\ :tc=daemon:
7. Generate the binary: cap_mkdb /etc/login.conf
8. Add kern.maxfiles=80000 to /etc/sysctl.conf
9. Run sysctl kern.maxfiles=80000 to set it immediately
10. Set ownership on Syncthing directory: chown -R _syncthing:wheel /var/syncthing
