The branch main has been updated by des: URL: https://cgit.FreeBSD.org/src/commit/?id=a401c8cb26b22688087ad7c5ee527718459df15a commit a401c8cb26b22688087ad7c5ee527718459df15a Author: Dag-Erling Smørgrav <des@FreeBSD.org> AuthorDate: 2023-10-05 14:50:01 +0000 Commit: Dag-Erling Smørgrav <des@FreeBSD.org> CommitDate: 2023-10-05 15:11:22 +0000 certctl: Split certificate bundles before processing. This allows 'certctl rehash' to do the right thing when ca_root_nss is installed, instead of linking the entire bundle to the hash of the first certificate it contains.
