The branch main has been updated by kevans: URL: https://cgit.FreeBSD.org/src/commit/?id=494e7dfdbe6ecfe572228ed39f5c794954da068c commit 494e7dfdbe6ecfe572228ed39f5c794954da068c Author: Kyle Evans <kevans@FreeBSD.org> AuthorDate: 2023-05-05 15:12:13 +0000 Commit: Kyle Evans <kevans@FreeBSD.org> CommitDate: 2023-05-05 15:28:40 +0000 daemon: EINTR from kevent(2) is not a fatal error Simply resume waiting for events rather than exiting if we took a signal here. This at least fixes running programs under daemon(8) in the face of suspend/resume, which I suspect hits us with a spurious EINTR rather than a signal anyways.
