Your discussion is pretty impressive and I have been reading it with care. Honestly, I am far from having a distant enough picture of the whole say to comment about what the discussion is about (and to be honest, I am not even sure I do know exactly what the point of the discussion is - please forgive me). But "Unix" has been available for MacOS users for a long time, far before MacOS X went out and using a Mach kernel. It has been since 1996, over a Mach kernel. Years ago, I worked for the crypto military branch of my country. We used Unix-based programs for some of our work. I had a Powerbook 190 and I needed Unix over it. After some time thinking it was not possible, I have found that MachTen did sold a Unix for x86 that worked upon a Mach kernel. You installed it on your MacOS and launched it from there. And you then had Unix running there, over a Mach kernel, with X too. You had both at the same time, running friendly together on screen and inter-operable. Vendors did not wait for Apple to let them run Unix software by using MacOS X. Before MacOS X got out, you could already run a Mach kernel over your Mac and compile almost anything there (anyway, all crypto programs I ever needed compiled there - it took a few monthes). I used it over MacOS 7.5.2 then 7.5.3 and 8.1 but I came back to 7.5.3 later. Motorola-based Powerbook with Mach kernel, happily compiling and running Unix programs with a perfect X working. I still got the product box and everything in mint condition : http://perso.wanadoo.fr/gilbert.fernandes/remembering2.html#190 The first MacOS X release went out in January 1999 (and the first public beta a year after, 2000 - I bought it from the Paris Apple Expo). I hope you will both find this information interesting. Most people I talk about MachTen product and running Mach kernel and Unix over my old Motorola-based 68k get pretty surprised about it. Now I got to start to read all this thread all again, so please excuse me. Looks like I'm going to need.. some time :o) -- unzip ; strip ; touch ; grep ; finger ; mount ; fsck ; more ; yes ; fsck ; umount ; sleep
