Last change on this file since 94ef58c was 27964fe, checked in by Alejandro R. Sedeño <asedeno@mit.edu>, 15 years ago
Fix pseudo-login interation with zephyr initialization. functions.c: owl_function_zephyr_buddy_check should bail if we don't have zephyr initialized. zephyr.c: owl_zephyr_finish_initialization should perform the initial pseudo-logins check if pseudologins is on.
