It'd probably be easier and less error prone to cut and paste (do you
know how?)

For ext2, just give it permissions the normal way, by chmoding the
files. (and make sure you/it has permissions on the /mnt/whatever dir,
of course.)

For vfat/msdos, use either the uid or umask options.  Since these
filesystems don't have permissions, these options tell mount what to set
them to.  


will tell it to create files with permissions -rw-rw-rw-


tells it to create files with owner as my user, which happens to have a
uid of 1000.  You'll have to use the numeric uids, it doesnt like

More details about this in the mount manpage in the section "Mount
options for fat".

(Are you starting the control panel tools from a menu in x or something
(ie. not by typing a command in the Wterm where you're root?)) Any
program started by another program (such as a shell) is usually run as
the same user as the parent program.  So you start X as your user, which
starts the windowmanager as your user, then when you, for example, click
on the control panel, it starts the control panel as your user.  The su
command doesn't turn you into root, it just starts a new shell where you
are root (su stands for SuperUser (or maybe SUperuser), not Switch
User).  So, try typing printtool or whatever in your su'ed wterm.
