We assume that you already have:
One "main" or "primary" Linux distribution installed that is running a 2.4-series or newer kernel,
sufficient disk space for the secondary installs (and any subsequent development/testing work).
/opt/distros/redhat_6.2/ suse_7.2/ mandrake_8.1/ debian-potato/ slackware_8.0/ |
where each directory contains the complete set of files resulting from each distribution install.
