commit 3041e6950d07f0d11c9f91fefbf3c273cbbe4407 Author: Kyle Evans <[email protected]> AuthorDate: 2023-11-22 04:41:36 +0000 Commit: Kyle Evans <[email protected]> CommitDate: 2023-11-26 04:08:40 +0000 lockf: hide unavailable error with -n -s The error message is expected, allow -s to suppress just that one since it would loosely fall under the definition of "failure to acquire the lock" described in the manpage for the -s option.
