Digressing a little bit here... reiserfs is a really good option. It's more robust than the ext3 filesystem.
did you notice any performance gains using reiserfs? i tried using it once, but was a bit apprehensive as i am used to ext3 now. you tried any other fs?
also i got my iptable query solved. i had a funny red-hat default chain which allowed all packets in. so had to insert the icmp drop rule rather than add it!!
i wanted to ask you on devfs, udev, and the current /dev directory. i am a bit messed up on these concepts. any good info/links? or better still could you explain some stuff.
