Question Small question about System.map and isolinux


I'd like to know if System.map is needed when using isolinux.

Like, if I make a simple bootable CD with a ramdisk and a kernel.

TIA

Hi win32sux,

My understanding is that System.map is used for the running kernel and has nothing to do with booting. This web page discusses System.map and some of its uses.

I was going to check to see what Damn Small Linux did, but I would have to shut some things down (that I don' want to do right now) to check that out. But I did look at the initrd they use. It contains a /boot symlink that points to their main filesystem (/KNOPPIX/boot) on the CD. I imagine that directory contains System.map. (Remember that they continue to use this ramdisk on the running system.)

Hope this helps.

Hi, blackhole54. Thanks for the reply. Yeah, I've seen that link before, it's pretty cool. Anyhow, I think you've given me a good idea, which is to look at some Live CD distros to see how they do it. Having a symlink from within the /boot directory on the ramdisk toward the System.map on the CD itself seems like it makes sense. I'll have to look into that. Thanks.
