...To be fair, let me also state that I'm using Fedora Live, with a 2Gb USB key as the boot drive. I am pretty sure that Fedora installed onto a fixed system disc would be less hinky. As well, as my prof says with a giddy grin on his face, Fedora is the Linux for Linux geeks... so it may well not be the most straight-forward version of Linux out there.
Back to your regularly scheduled Sunday, and I'll get back to my shell scripting. Carry on! :)
