The branch main has been updated by jlduran: URL: https://cgit.FreeBSD.org/src/commit/?id=f1de49f508714b024ac6f3a60845108f81c7aee7 commit f1de49f508714b024ac6f3a60845108f81c7aee7 Author: Jose Luis Duran <jlduran@FreeBSD.org> AuthorDate: 2026-05-27 00:15:39 +0000 Commit: Jose Luis Duran <jlduran@FreeBSD.org> CommitDate: 2026-05-27 00:15:39 +0000 nanobsd: Offset code partition to a track boundary Ensure the primary and secondary code partitions start at a proper track boundary by applying a NANO_SECTS offset in bytes. While track-boundary alignment is largely obsolete on modern storage, this change maintains compatibility with current images (legacy). A future commit will transition to 1 MiB alignment boundaries.
