The branch stable/12 has been updated by kevans: URL: https://cgit.FreeBSD.org/src/commit/?id=5cf1ba21eebaf89cf4d8639a18345dc49116d1d5 commit 5cf1ba21eebaf89cf4d8639a18345dc49116d1d5 Author: Kyle Evans <kevans@FreeBSD.org> AuthorDate: 2020-12-17 03:42:54 +0000 Commit: Kyle Evans <kevans@FreeBSD.org> CommitDate: 2020-12-27 20:50:53 +0000 MFC freebsd-update: unconditionally regenerate passwd/login.conf files The existing logic is nice in theory, but in practice freebsd-update will not preserve the timestamps on these files. When doing a major upgrade, e.g. from 12.1-RELEASE -> 12.2-RELEASE, pwd.mkdb et al. appear in the INDEX and we clobber the timestamp several times in the process of packaging up the existing system into /var/db/freebsd-update/files and extracting for comparisons. This leads to these files not getting regenerated when they're most likely to be needed. Measures could be taken to preserve timestamps, but it's unclear whether the complexity and overhead of doing so is really outweighed by the marginal benefit. I observed this issue when pkg subsequently failed to install a package that wanted to add a user, claiming that the user was removed in the process. bapt@ pointed to this pre-existing bug with freebsd-update as the cause.
