help me understand the symlinks on /ramdisk

[als]

Hi all,

When booting knoppix from CD, I see a line that says:

Creating directories and symlinks on /ramdisk...Done

But I can't find that step in the init scripts anywhere.

I want to build a box that will boot from the hard drive, but basically treat the hard drive like a read-only filesystem (just like the CD). It should mount /dev/hd? as ro, so the system coudl be used (and abused) and then be recovered with a reboot.

Can anybody give me a hint on how the root filesystem and all the symlinks on the ramdisk are created when bootinf from CD, so I can mimick it with a hard drive install?

Thanks!

Al
