The branch stable/14 has been updated by rmacklem: URL: https://cgit.FreeBSD.org/src/commit/?id=caf162412dbc74e71ca2ac02e2a8a96e5e086f47 commit caf162412dbc74e71ca2ac02e2a8a96e5e086f47 Author: Rick Macklem <rmacklem@FreeBSD.org> AuthorDate: 2025-08-26 01:38:54 +0000 Commit: Rick Macklem <rmacklem@FreeBSD.org> CommitDate: 2025-09-09 00:52:16 +0000 exports.5: Add a paragraph clarifying the use of "V4:" The exports.5 man page is a bit of a monster. One place of common confusion is the use of the "V4:" line(s) for defining the location of the root of the NFSv4 export subtree. This patch adds a paragraph in an attempt to clarify this. This is a content change.
