This revised system test is superior to the one accepted when #61744 was closed because it confirms whether the configured limits are actually being enforced upon login. The previous test merely validated the serialization of one particular config in the config file. * gnu/tests/pam.scm (pam-limits-service): Revise test to confirm limits on login. (%test-pam-limits)[description]: Update. (%test-pam-limits-deprecated): Remove. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
