The caching functionality of nodes.conf, and the optional persistence functionality that came with it, appears to have been preventing actually writing the configuration to disk in all cases. This change fixes the ability to write to nodes.conf. Somewhat opinionatedly, this change removes the caching functionality of nodes.conf. The tests have also been updated to use real files for i/o rather than tying into the caching system, making them more accurately test the ability of Warewulf to actually read and write its configuration.
