Re: Setting Linux Kernel Parameters

Lovely. That's really useful, so thank you.

But it unfortunately doesn't tell me *how* to modify those parameters, which is what I actually needed to know. The structure of those files looks a bit tricky, and I don't want to bodge them up. It then also says 'if you modify them, rebuild the kernel', which again I'm sure is sound advice, but it doesn't say *how* to do that.

If these aren't steps which are easily describable, then fair enough: if I have to get the Big Boys Book of Linux for Windows Users out of the library, I'll do it. I just thought maybe it wasn't that tricky... ?
