Ran zpool upgrade, need to update boot code?

[os914964619]

I am running the latest Opnsense and decided to run zpool upgrade. Here was the result:

root@router:~ # zpool upgrade zroot
This system supports ZFS pool feature flags.

Enabled the following features on 'zroot':
  userobj_accounting
  encryption
  project_quota
  allocation_classes
  resilver_defer
  bookmark_v2
  redaction_bookmarks
  redacted_datasets
  bookmark_written
  log_spacemap
  livelist
  device_rebuild
  zstd_compress
  draid

Pool 'zroot' has the bootfs property set, you might need to update
the boot code. See gptzfsboot and loader.efi for details.

Is there anything I need to do, or can I reboot? I am worried that I'm going to brick my opnsense install by not updating "the boot code".

You should update the boot code. The details are in the mentioned man pages. 

OK, let's start with the output of zpool status and gpart show, please. Do you know if your system boots legacy or EFI?

What feature or flag you need desperately ? Playing with zpool upgrade without backup is something not recommended.
I would definelty not upgrade zroot atleast.

Any fresh install will create a zpool with all these features enabled, so why not upgrade your existing one if only to get rid of that message in `zpool status`?

I prefer consistent state.
