Moving database files to larger partition?

[Jay Paulson]

I'm currently setting up MySQL 4.1.2 on RHEL 4.1 and I have found the
/etc/my.cnf file.  I'm trying to find out if I change the "basedir" from:

Basedir=/var/lib

To

Basedir=/other/path

Will that move the actual data files that have all my databases?  Do I need
to move any of the things that are in /var/lib over to the new path or just
the data files of my databases?

Thanks!
