2024-03-31 r/7835 feat(automatic-gc): robust way to disable automatic-gcVincent Ambo1-0/+5
We just had a minor incident where apparently our build cache for the critical security fix was deleted by automatic-gc (which I had stopped manually) being reenabled by an unrelated whitby deploy. This adds a new mechanism where by touching a file called `/run/stop-automatic-gc` the GC can be prevented from running. We might want to configure an occasional alert or something if this file exists, so we don't forget about it when we are using it.

This will require the daemon to be running when launching GC, but won't start it if it happens to not be running for some reason.

2021-04-14 r/2511 feat(ops/modules): Add module for automatically collecting garbageVincent Ambo1-0/+90
Adds a module that automatically collects garbage based on disk space thresholds, and configures it to run hourly on whitby. This is implemented as an alternative to cl/2937, which I've been told uses a Nix feature that doesn't actually work. Under-the-hood this is simply a systemd timer running a shell script which checks available disk space and runs GC when necessary.
