Seriously, what do you mean "changing in linuxconf"? Editing /etc/fstab?
Backup, format partition with reiserfs, restore, run lilo. There is one
point - by default reiser mounts with tail conversion. It has potential
problems with grub (if you are using it) and is known to be slower. You may
consider putting notail as mount options. Unfortunately, it is not possible
when installing.
