"An > operating system" in general may or may not be; [...] It's true there was a certain amount of "under OS X" context for what you wrote, since the last sentence is obviously false for many non-OSX OSes for which the first is true (consider, eg, System 7 for 68k Macs). I read that context as applying to only that last sentence, and my "in general" was at least partly an attempt to make that explicit; apparently I wasn't explicit enough to make my meaning clear. I'd argue with your "very nice guy" a little even for OS X, though, since there is a substantial amount of Unix basing in the libc layer, which is used by much more than just the CLI; of the three components listed, it would have to be part of the core. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B _______________________________________________ Fun and Misc security discussion for OT posts. https://linuxbox.org/cgi-bin/mailman/listinfo/funsec Note: funsec is a public and open mailing list.
