That is the behaviour when the "setuid" bit hasn't been set on the
"mount" executable (and maybe neither on "su"?).
Please check if the attributes are as follows:
-rwsr-xr-x 1 root bin 68804 2004-05-27 23:26 /bin/mount
-rws--x--x 1 root bin 35780 2004-06-21 21:20 /bin/su
^ note those "s"es there (instead of "x")!!
This means the program has the right to run as ROOT, no matter
what user starts it. In octal, the attributes are:
4755 (for mount) cq 4711 (for su) and if they aren't like that in
your system, please change them back:
chmod <octal_value> /bin/<command>
as root.
PS: the OWNER of those commands must also be "root"!

I used partimage, and also copied files, I can't remember exactly anymore...

I did this; I saw that not only had some permissions changed, also some
file-owners and file-groups had changed, so I've decided to reïnstall, it
was time anyway to choose some different packages for my computer. Should
have done it immediately of course

Anyway, thanks a lot for all the info, if nothing else I learned a lot!
