Well with current install tools it isn't easy to do. It is FASTER, but less
efficient on storage. How much less? Worst case is less than double
required, and for that you need a host of files that are one block plus one
byte. The B-tree overhead is the same or less.
To make it happen you install a / only system with lotsa unused space. The /
can be reiser--that's automatically a notail mount.
Then you create /var /usr /home and other partitions manually, and format
them reiser.
Then you edit /etc/fstab and make them mount points like /spusr /spvar /sphome
/dev/hda7 /spusr reiserfs notail 1 2
/dev/hda8 /sphome reiserfs notail 1 2
/dev/hda9 /spvar reiserfs notail 1 2
Of course the partition designations will vary with your mileage.
Mount them and
mount /spusr && cp -a /usr/* /spusr && umount /spusr
mount /spvar && cp -a /var/* /spvar && umount /spvar
mount /sphome && cp -a /home/* /sphome && umount /sphome
Now edit /etc/fstab again and remove the 'sp' from the mount points
then
mv /home /oldhome && mkdir /home && mount /home
mv /var /oldvar && mkdir /var && mount /var
mv /usr /oldusr && mkdir /usr && mount /usr
Delete the /oldxxx directories at your leisure, bring in urpmi or similar or
just use your install CD and run Update to load the amount of system you want.

Please note that if you do not use the install disk in update mode, you never
even need to reboot.
