The branch stable/14 has been updated by olce: URL: https://cgit.FreeBSD.org/src/commit/?id=6e888a22743f67d3b130dd0a9b9849bcee160d2f commit 6e888a22743f67d3b130dd0a9b9849bcee160d2f Author: Olivier Certner <olce@FreeBSD.org> AuthorDate: 2025-09-01 09:31:23 +0000 Commit: Olivier Certner <olce@FreeBSD.org> CommitDate: 2025-10-10 17:15:55 +0000 jail.2: Mention EPERM is returned on open directories The manual page does not directly mention this reason for getting EPERM, instead referring the reader to chroot(2). We have had some questions about it recently, in part due to a bug (fixed), and this case is not an obvious permission/problem, so let's be more explicit.
