not only i do not, no one has be root when making an iso.

*but* ever one needs to be 'root' user when editing files owned by
'root, as is case of loop mounting an iso and editing boot.conf, which
is main of this thread.

i started to remove "linuxnewbie82's" comment on mkisofs, then i thought
that Kevin should be aware of "linuxnewbie82's" comment, and the mkisofs
instructions following on page, presuming Kevin would read rest of page.
