The script itself is of not interest -- it is just particulars -- that
i can change even right on the target machine, though it is hard to do
for many lines and w/o mcedit at least, not to say graphical editor --
w/ the everywhere existing nano! :o)

I simply wonder the phenomena. And having not found the answer myself,
would ask more experienced users of "Gentoo".

It is not always required. So, this part could be done manually still
whereas the rest -- automated, like usual installer does.

Again, nothing keeps us from using several commands to compile
customized kernel, starting w/

/usr/bin/make menuconfig

Of course! Best practical knowledge should be accumulated in the
documentation and included as default presets for the installation or
later system administration.

You remember, i did rise here question on profile customization? -- So,
i thought out that base profiled is too "thick" to be called base or
default. I think, only working kernel, package manager and network
-- speaking of installed and self booted system -- should be installed
and called base/default and from that base all other profiles grow.
Also, all those other profiles should not to be as next step to
develop and grow the installation, but checklists of packages
w/ corresponding checklists of the packages dependencies -- just like
"Debian" does for its compiled packages w/ that differences, that
choosing process will be followed not downloading and installation
only, but compilation also. -- These i call "all about choice", so that
user/admin had not to fight w/ the profiles that are totally
unnecessary at wide angle of view, but rather add some automation for
the lazy -- like client wants KDE suite -- alright, get it -- and so
forth. But for the concerned, are those checklists of packages -- when
everyone can choose what is desired likewise USE, CFLAGS -- all through
checklists, so that the user will not search the web for the well known
stuff, but right in the system configuration might see all that is
available w/ comments on what and why it does, as well as pros and cons
that follow the choices.

All this simplifies the process of installation and farther support of
systems. Nobody likes to wade through the oceans of routine but rather
make something fast, reliable, new, etc. But routine just scares away.
