From d8e59012e29dee301a7af5c2a70749637319fafc Mon Sep 17 00:00:00 2001 From: Colin Percival Date: Sat, 31 Oct 2020 03:36:31 +0000 Subject: Attempt to defuse a land mine before anyone else steps on it: The freebsd-boot partition is not always the first one. Following the instructions in UPDATING resulted in my overwriting the efiboot0 partition on my laptop with ZFS boot blocks, which had negative effects on the system's bootability.
