Nothing major. I may have missed some of those in my initial review. Nice doc overall.

I'd use the month itself instead, if known. (Not all our users are in the same hemisphere.)

567–568

Instead, I'd use % (not root) or # (root) shell prompts as done in the rest of the handbook and stated in https://docs.freebsd.org/en/books/handbook/preface/#preface-conv .

638–646

I'd like someone more familiar with QEMU and system administration than me to look at the use of sudo here. I'll just note that to me it sounds inconsistent with the suggestion to add a -runas option below.

Same remark here as for the sudo in left.sh above.

859

And again re sudo

1083

If you keep the sudo in left.sh below, do you also need the one here?

1091

Same here re sudo in scripts.

1137

1217

Here too I'd use the month if known.

I've removed all the "sudo" statements and replaced with the root prompt "#". The "-runas" option is designed to run the QEMU command but drop privileges before running the VM.

From QEMU(1):

-runas user
       Immediately before starting guest execution, drop root
       privileges, switching to the specified user.

698

edited as "... metadata during first use" instead of "metadata during the first use".

1083

I've changed out all "sudo" and replaced with the root prompt "#".

1091

Same as above. Also, in this example I removed the text
"# left VM script" since it could be misunderstood as a command run as root.

I did the same for the script listing at line 853.

Seems like the latest diff hasn't been uploaded yet, but once it is uploaded, I think this is ready to land?
