As I see, total mimumu subset (new term:-)) is in req & imp section from
kernel through editor & comiler 2 package manager, so this is the real
base (minimum, required?) system, isn't it?

ok: base system=Req + Imp + these essential tagged packages, Very THX :-)
but remaining question:
msgid "Installing core packages"
what are `core packages'? I don't understand this term absolutely &
cannot resolve its meaning strongly getting the difference related to
`Req + Imp packages' or `whole Base System' or `just Essential packages'.
