I have a pc clone with an lfs version6.3 os that was builded from a live CD. It got on the internet
today with Lynx (27mar09). Surprise! Surprise! Thanks to all involved from various time periods and
various places on the internet. Large and small this and thats from HoWTO's and tutorials and forums

gave it away once. Glad...
