		the "all" should be removed here. Maybe this should be

I wonder whether it wouldn't be better to add the second paragraph to a
new manpage section that discusses inode numbers more thoroughly. Maybe
a new "INODE NUMBERS" section below the "SERVICE FORMATTING AND
DELIMITERS" section. Then you could have the "nounix" and "serverino"
options refer to that section.
