Got .5 installed on a 500MB hard disk.
Not a bad distro I might add...I really liked the upgradeability aka package management. However, if I hadn't been a slackhead from way back...I might have been a bit put off at the beginning do to lack of direction. However, the forums and man pages worked great. Like I said though, if I were used to something like Windows, I'd have been put off bigtime.
Something I've been harping on for about a month now for newbies is MEPIS Linux. It's like knoppix...so it is put over the top of debian and uses the apt package management system and it is a LIVE CD. However, the option to hard disk install is better than in knoppix and the thing that got me with it is the hardware detectablility. I m ean, it detected my CDRW USB...something NO linux distro has ever done, including knoppix.
So add those two cents to yours and we get four. There is our four cents. Two really great Distros that are up and coming. Arch Linux and MEPIS Linux. :)
