I think this is a false-positive warning, that shouldn't be fixed in this
way. That file is not one to be put at the top level of the doc - instead
it is included by both freesd and linux gsg guides within the relevant
sections. If we can't suppress this warning, maybe we need to rename the
file to not end with a .rst extension.

Ok, it's not a big deal anyway, RHEL 8.4 is using an old version of 
sphinx (1.7.6). I can't reproduce on Fedora with a newer version (3.4.3) 
and no one else seems to see it.

I tried to remove the warning with :orphan: but I'm not sure it's that 
well supported in that version. Removing the .rst doesn't seem like the 
right thing either. I'm ok to live with the warning on older sphinx. 
Thanks for replying.

Kevin.
