Sun, 18 Oct 2026 21:06:48 +0200

bsdinstall: use the GPT label for swap in fstabThe GPT layout already labels the swap partition swapN, but fstabnamed the disk device. That name changes when disks are added orreordered, and swap does not come up until fstab is edited. Write/dev/gpt/swapN instead, appending .eli when swap encryption is on.Mirrored swap still uses /dev/mirror/swap, with the same suffix.Submitted by: Wanpeng Qian Reviewed by: kevansDifferential Revision: https://reviews.freebsd.org/D32936 List of files: /freebsd/usr.sbin/bsdinstall/scripts/zfsboot

bsdinstall: Add loader.efi to all ESPs we createFor proper redundancy, add copies of loader.efi to each of the ESPs wecreate when we create multi-volume ZFS datasets. zfsboot creates a listof secondary ESPs, while bootpart doesn't create any (it's the UFSpartitioning tool) because we don't supporg UFS over gmirror. Theprimary ESP is mounted and is what we use efibootmgr to boot from. Theredundant copies allow the system to boot if the primary disks fails.Sponsored by: NetflixMFC After: 2 daysPR: 208802Reviewed by: cpercivaDifferential Revision: https://reviews.freebsd.org/D52780 List of files: /freebsd/usr.sbin/bsdinstall/scripts/zfsboot
