installation opinions

[Paul Kaplan]

I'm installing kubuntu onto a new system dual booting with win2k.  I'm going 
to planning to have / and /home on separate partitions, but I want to 
maximize the size of /home and still allow for future growth under / as I 
install new software or upgrade the distro over the next 3 years.  I'm 
looking for opinions on the minimum / partition size for a kubuntu install 
that would still allow for future growth.  Is 6Gb to small?  8?
TIA
Paul
