Bug ID: 293912
Summary: Handbook: section 22.3.11. wrong gpart instruction
Product: Documentation
Version: Latest
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: Books & Articles
Assignee: doc@FreeBSD.org
Reporter: jd.fbsd@goneja.de
The Handbook says in section 22.3.11. Upgrading a Storage Pool
https://docs.freebsd.org/en/books/handbook/zfs/#zfs-zpool-upgrade
"""
For systems using EFI to boot, execute the following command:
# gpart bootcode -p /boot/boot1.efi -i 1 ada1
"""
Please remove these lines.
This destroys the EFI partition, so that the computer cannot boot from it
anymore.
The correct instructions would be:
"""
# mount -t msdosfs /dev/ada1p1 /boot/efi
# cp /boot/loader.efi /boot/efi/EFI/BOOT/BOOTX64.efi
"""
But I think, updating the EFI loader should be explained in more detail
somewhere else in the Handbook.
