Newbie-level question, I'd guess: what is lsattr listing
that ls alone is not? Is there an ext{2,3} attribute called
'immutability' that goes above and beyond the rwx

Presumably one can make a file mutable again, right? So
would this add much security to /etc/sudoers?

Maybe sudo is supposed to be portable, so they insist on
abstracting above the details of filesystems. Maybe?
