[-- Attachment #1 --] Hi, Currently, FreeBSD’s pkg installs software by uninstalling the old package before installing the new one. This approach has broken my system, because the new package failed to install while the old one had already been removed. I believe it would be safer if pkg could automatically create a snapshot of the last bootable system using ZFS or UFS before making such changes. ykla Graham Perrin <grahamperrin@gmail.com> 於 2025年8月28日 週四 下午12:48 寫道： > In addition to packages that already have it: > > - which packages might benefit from the vital flag? > > An initial shortlist of candidates: > > FreeBSD-caroot (main, not (or not yet) stable/14) > FreeBSD-certctl (stable/14) > FreeBSD-kernel-generic > FreeBSD-kernel-generic-mccam > FreeBSD-kernel-generic-nodebug > FreeBSD-kernel-minimal > FreeBSD-pkgbasify > FreeBSD-pkg-bootstrap > FreeBSD-rescue > FreeBSD-utilities > > main branch, unless specified otherwise. > > > Background > ========== > > On 11th May 2025, Baptiste Daroussin wrote: > > > Le 11 mai 2025 17:29:49 GMT+02:00, Mark Millard <marklmi@yahoo.com> a > écrit : > >> In a system/chroot that is based on PkgBase, a "pkg delete -a" > >> that is allowed to run also destroys the system software, not > >> just port packages.
