Sorry O-P, something of a misunderstanding there. What does my brain in sometimes is the system of permissions in Linux. And it does it in simply because I don't know enough about it and the explanations I've seen have taken too much for granted. I'd be grateful to have it explained to me in the sort of way I've seen you explain things so many times to people on this forum. As I said, I suspect there are a lot of others like myself in this regard. This all came out of my exchanges with you and with pags about the permissions situation on that external hard drive I was setting up. (http://www.pclinuxos.com/forum/index.php/topic,77481.0.html
) And if, in addition, you had the time to do as you've said - i.e. talk about 'setting up a separate boot partition, and interesting things one can do with one to get around older BIOS limitations and such' - then I think that too would meet with the approval of a lot of people. And in any case, thank you for your offer.
