[RndTbl] File system question again

Just so I get it right, could someone tell me how much disk space to give "/" ? I'm installing Red Hat 7.2 and I've got 14 gigs of extended space on the hard drive. This is the intended plan: /dev/hda7 / space ? hda8 /boot 100 megs hda9 /var 3 gigs hda10 /usr 8 gigs hda11 /home 100 megs hda12 /swap 2 x memory = 768 megs Can I expect any complications from Red Hat 7.1 boot menu? I suspect its taken over the MBR. That's one reason I have not wiped RH 7.1 though its practically useless now. I hope its not holding my Win98 and Slackware7.1 hostage. Any advice would be very welcome. I'd like to get RH7.2 going this weekend.
