     Not very good; you'll have problems with symlinks, special files in 
/dev, etc. Try:

umount /dev/hda1
mke2fs /dev/hda1
mount /dev/hda1 /mnt
umount /home
cd /
find ./ | grep -v /mnt/ | cpio -pdmv /mnt

Edit lilo to point to your new root and reboot. After reboot:

mount /dev/hdb2 /mnt
rm -rf /mnt/*
cd /usr
find ./ | cpio -pdmv /mnt
umount /mnt
rm -rf /usr
mkdir usr
mount /dev/hdb2 /usr

     If you don't have enough space in /dev/hda1 to hold everything, you 
can take a few more steps to copy directories individually instead of all 
your tree. The key is to use cpio and to *always* exclude the destination 
directory from the list of files to be copied (otherwise, you'll just 
fill up your disk). Check the line

"find ./ | grep -v /mnt/ | cpio -pdmv /mnt"

 It tells you everything.

See ya,
