I’m running nixops on GCE, and for months it was fine. Lately, I noticed that for some reason the website started going down. What I noticed is that for some reason, every few days, all the services are gone!
The services exist in /nix/store but for some reason they disappear from /etc/systemd/system.
I don’t get how that happens. I tried recreating it by rebooting, or by force rebooting, but nothing I do causes this.
My only computer which controls this deployment was off when this happened, so it couldn’t be a client-side issue.
What could be causing this?
