Picture someone doing a full virgin install of FreeBSD on their hard disk.
Then imagine them making a full CDROM copy of that file system. Thus the
"live filesystem" -- that is mostly what the second CDROM is. That's why
you get the /tmp directory on the CDROM. I kinda like it. If/when someone
messes with permissions and settings you can refer to the CDROM to fix it.
Many people also want to play with say the source code, but don't want to
devote large quantities of disk space to it. So you can make symbolic
links from your hard disk's file system to the CDROM (assuming you have it
mounted) and you can play with the source all you want. Personally I was
thrilled when they added the second CDROM with FBSD 2.0.5! There is a nice
utility called linkdirs (or something like that) that comes with the X11
distribution (if you installed it).
Come to think of it, that script would be a nice thing to place in /tools
or somewhere more accessable on the first CDROM. (Jordan?)
