The configurations that are detected would only be the defaults, any
user who wanted to change them, or bypass the entire install
alltogether, could still do so. Indeed, you could specify a boot option
like noinstaller and do the install the old way, or flip over to another
vc  (the installer would presumably be on vc/1) and continue the install
by the guide instead of the installer.

Its important to note the last thing that an installer would do would be
to impose itself on the user. Its purpose is to provide some level of
confort and prettyness for those who would like it, and to detect the
most optimal defaults for a system, however, not to take away from the
user the ability to change these defaults.

hmmm, perhaps having global use flags based on the selected packages,
but have each package have the ability to override those USE flags when
slelected? (default setting would be whatever global USE is)

heh....not for telnetd, just for telnet, since most people when trying
to test connectivity or something, or even just to see a banner remotly
will just telnet to the port to see whats there. The intent here is not
for the person to be running telnetd
