I think I may sometimes take too much for granted, owing to the fact that, at the end of the day, I own every system I work on. Therefore, I tend to miss things. I think I'll go away and read your article, and ponder the consequences. It might also serve me well, in light of the fact that I plan to write more, to have a box and effectively "forget" root on it, test any future writeups there before I run off an go moggy with the text editor. Thank you for the pointer. Much obliged.
