Posting direct links should be absolutely fine, IMO. My fiancee shares my frustrations with LMGTFY responses; she'll google for a phrase, and the first few results will be forum and newsgroup mirrors of threads along the lines of: "How do I do $x" "Google for "$phrase_just_googled_for" > >>> alternatively you could use catalyst: >>> http://www.gentoo.org/proj/en/releng/catalyst/ >>> >>> or you just mount the iso, modify it, run mkisofs on it and burn it. >>> the mkisofs options you are looking for are -b and -c. >> >>I knew there was going to be something I wasn't going to know, and it >>looks like the values passed to -b and -c are it. > > again, the hint you maybe didn't get was: you will have to do some of > the work yourself. If I wasn't willing to do some of the work myself, I wouldn't be using Gentoo. I'd be using Ubuntu. Or wearign diapers.

Huh. Ok; when I glanced through the man page for mkisofs, I got the impression that the files added by -b and -c wouldn't appear on the filesystem. I don't know how El Torido actually works, at the ISO level, I only know it's something like a bootable floppy image that a capable BIOS loads and executes. -- :wq
