couple questions about ks.cfg entries

[rpjday <rpjday mindspring com>]

  first, what is an "interactive" install?  i'm guessing that it
means, if i skip specifying some option (such as mouse type), i'll
be prompted for it.  is this correct?

  second, and more philosophically, i'm confused by the aesthetics
of the "zerombr" option.  if you select to clear the mbr, the line
"zerombr yes" is added to the ks file.  if you choose not to, *no*
line is added.  this seems inconsistent with the way other boolean
options are specified.  for example, "reboot".  you either get the
line "reboot" or you don't, depending on what you want.  so why
do you not similarly get the line "zerombr" or not?  what's the
purpose of the additional word "yes"?
