I found a post about suspending and then going into hibernate that included a really clever script. Turns out that with NixOS this is even esaier to coordinate as you have systemd so can have a before and after service. I just include this in my /etc/nixos/configuration.nix file and nixos-rebuild; then a systemctl suspend or a close of the lid will cause the hibernate timer to be set.

Semantic Commit Messages

See how a minor change to your commit message style can make you a better programmer.

Format: <type>(<scope>): <subject>

<scope> is optional

Example

oprypin

Save these files as ~/.config/systemd/user/some-service-name.*

Run this now and after any modifications: systemctl --user daemon-reload

Try out the service (oneshot): systemctl --user start some-service-name

Check logs if something is wrong: journalctl -u --user-unit some-service-name

Start the timer after this user logs in: systemctl --user enable --now some-service-name.timer

Proxmox VE 6.x release includes a feature to add custom cloud-init configs. Unfortunately there is poor documentation, so I had to figure this out by adding pieces of information together.

The custom cloud-init files (user-data, meta-data, network-config)

The cloud-init files need to be stored in a snippet. This is not very well documented:

1. Go to Storage View -> Storage -> Add -> Directory
2. Give it an ID such as snippets, and specify any path on your host such as /snippets
3. Under Content choose Snippets and de-select Disk image (optional)
4. Upload (scp/rsync/whatever) your user-data, meta-data, network-config files to your proxmox server in /snippets/snippets/ (the directory should be there if you followed steps 1-3)
