Big thanks to John and Stroller, for helping me get some kind of grip on what the real issue (not to mention nomenclature) of my project is. Both of you mentioned a few issues. One thing: I'm not in a huge rush. I should have started this months ago, but that's irrelevant now. That's why I'm asking questions and reading. I need a system at home that enables me to do outrageously accurate work as rapidly as possible (that's the holy grail in data migration, it seems), so, cutting corners, or impatience, now, will kill me sooner rather than later. Stroller, you mentioned Gentoo 'not being for the faint of heart". Is that due to lots of using 'ln' and configuring rc files and whatnot, as in not very 'automated'? That doesn't put me off either, but, for all i know, there might be another issue, or issues, that I'm unaware of re; the gentoo (tricky) thing. I don't have X11 on the Mac now. I trashed it a couple years ago when I gave up on the idea (at the time, which was strictly out of curiosity). Apple no longer distributes X11 for Jag, (they don't have any problem with keeping the HFS+ filing system, the pathetic 'Finder', increasing their use of resource forks, or depending upon an 'extension' to identify content of a file, though, go figure). Maybe X11 is on the Installers for jag, i'll check, but, if not, then what? If I decide (very likely) to forego the Aqua/GUI and start out with a clean Darwin install, I should look for a rooted x86 install, no? Or can I go with KDE (which actually has all the XML apps, not Gnome as i mistakenly 'remembered'), right on top of Darwin? And last but not least, the 'distros'. Can i start with a clean drive, or do i need some basic architecture as a foundation? These must seem like pretty pedestrian questions, but it's been my experience that thinking i know/understand more than i do, is always a negative, further up the road. The documentation onlne is either on par with my knowledge (thin) or way over my head, it seems. About 18 months ago a friend gave me an 8-CD set that was a Red hat installer. Now, that must sound ridiculous. It looked it. I thought, "what sort of unix needs 5+ GBs for an istall????". I started out as a troubleshooter on mid-70s IBM big boxes, and 5GBs would have hld all of IBM's worldwide stuff. (ok, maybe not, but still, my 667 back then would have been the size of a Sears store, i think). Lots has changed, hasn't it? Anyways, thanks again, a lot, and i'll go have a look at Gentoo and a couple others... brian s.
