The branch main has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=494de51bc0074472d1b01604f085daea0844f240 commit 494de51bc0074472d1b01604f085daea0844f240 Author: Warner Losh <imp@FreeBSD.org> AuthorDate: 2025-09-30 02:46:57 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2025-09-30 02:55:46 +0000 bsdinstall: Add loader.efi to all ESPs we create For proper redundancy, add copies of loader.efi to each of the ESPs we create when we create multi-volume ZFS datasets. zfsboot creates a list of secondary ESPs, while bootpart doesn't create any (it's the UFS partitioning tool) because we don't supporg UFS over gmirror. The primary ESP is mounted and is what we use efibootmgr to boot from. The redundant copies allow the system to boot if the primary disks fails.
