The branch main has been updated by emaste: URL: https://cgit.FreeBSD.org/src/commit/?id=c0f52443166ae7ecd512ab0350469d9c3648788c commit c0f52443166ae7ecd512ab0350469d9c3648788c Author: Ed Maste <emaste@FreeBSD.org> AuthorDate: 2023-09-12 02:59:30 +0000 Commit: Ed Maste <emaste@FreeBSD.org> CommitDate: 2023-10-18 14:48:58 +0000 freebsd-update: handle directories changing to files Further to f6d37c9ca13f ("freebsd-update: handle file -> directory on upgrade"), handle the reverse case of a directory changing to a file. We may not encounter this case on upgradess (before freebsd-update is retired) but it is needed to support rollback.
