From 97cb43e732a38758c95b7caf3963507188d011cf Mon Sep 17 00:00:00 2001 From: Maxim Cournoyer Date: Tue, 9 Aug 2022 23:06:16 -0400 Subject: tests: configuration: Add a test to cover 'unset regression. The regression was introduced with a2b89a3319dc1d621c546855f578acae5baaf6da, and introduce a risk that 'unset leaks to serialized configuration files. * tests/services/configuration.scm (maybe-symbol): New type. (config-with-maybe-symbol): New configuration. ("symbol maybe value serialization, unspecified"): New test.
