ok

extreme bad idea if you have users

extreme bad idea unless oyu have specific applications
that will run that requires /tmp to be that big
most apps uses less than 100mb of /tmp or /var/tmp or /usr/tmp

wow .. you're collecting tons of log data ??
- how much data do you have now in /var/log
> /var - rest of the disk - logical
extreme bad idea ... unless you have users
- if you are intending to make a complete debian mirror
in /var/apt and equiv .. than it might be okay, but i'd
separate /var for users vs /var for system to keep itself running
you cannot ever provide enough disk space for uwers or your own
applications .. you will always run out of space ..
some apps require /opt in which case / is too small

or xfs or jfs ..
for disks that are say 500GB or more ... i'm not even gonna try
using ext3 ...
for partitions over 2TB ... its gonna be a fun testing game of
which apps crash first because it used the wrong libs
> How should I go about it???
manually fdisk it ... or write a small script ( 5-10 minutes )
write a 2nd script to copy over the data
mount /dev/somthing newdisk
cp -dpar /lib /boot /bin /sbin /home /var /newdisk
sync
chroot /newdisk
rerun lilo or grub or dd the mbr
reboot
