sudo? Never heard of that, and it seems I don't have in on my machine.

Yes you're right, I forgot to mention that.

Yes that will be reason, I never thought like that :-)
I think chmod is the best, well certainly the fastest, I don't know what sudo 
does, but kdesu pops up a window and asks for the root pass and tells which 
command will be executed, so the 'bad' things about it are that you need X, 
you need the kdelibs and the kde base/core too of course, and well it's 
slower of course, while with chmod you do it once and the user has access, so 
if you think carefully before you chmod something so that it can be used by 
users too there shouldn't be a problem.

Yes I agree that would be a better, but on my machine for example that 
doens't matter, so I normally use 666, and therefor typed that in the mail 
too, while u+s is better I think.

Really? Since I always shutdown using 'shutdown -h/-r now' I haven't tried 
that out, I had no idea of this. Seems nice, I'll try it out this evening, 
thanks. If it's like you say - which I don't doubt about - then then menu 
thing I describe is useless, since keybindings are faster.

A sync? I'm sorry, my English is really bad, I don't understand what you mean 
by that :o

Thanks for your explanation.
