Just updated my flake inputs for the first time this year and had to tinker for a bit.

The API for persisting files in the home directory changed, now disallowing the persisting directory to point to a home.persistence."/persistentPath/home/paulemeister/" as it now calculates that path automagically, when using home.persistence."/persistentPath

Also now the hm module is automagically imported through the nixos module. Gotta remove the import in you hm config.

It's really nicely done though with assertions. Just a heads up
