Editing the kernel commandline is described centrally in the bootloaders
chapter. Refer to it where appropriate (qm-pci-passthrough.adoc).

Additionally update the documentation on ZFS as rpool to the inclusion of
`systemd-boot`

Bootloader
~~~~~~~~~~
The default ZFS disk partitioning scheme does not use the first 2048
sectors. This gives enough room to install a GRUB boot partition. The
{pve} installer automatically allocates that space, and installs the
GRUB boot loader there. If you use a redundant RAID setup, it installs
the boot loader on all disk required for booting. So you can boot
even if some disks fail.
NOTE: It is not possible to use ZFS as root file system with UEFI
boot.
Depending on whether the system is booted in EFI or legacy BIOS mode the
{pve} installer sets up either `grub` or `systemd-boot` as main bootloader.
See the chapter on xref:system_booting[bootladers] for details.
