Good question.

Actually, I'm going to digress a little. What I'd love to see is
securelevel stay a slider, and the sysctls control what gets turned on at
different levels. I think the tree levels we have, "wide open," "snippy,"
and "anal," are fine. With sysctls, an admin can set what's turned on at
the different levels.

Admittedly one sysadmin could set securelevel 1 to be as picky as what the
defaults set to secure level 2.

Not sure how practical these thoughts are, but there they are. :-)

Take care,
