I have been using DSL for 1 yr and its really great. One concern of mine is if i install DSL in multi user mode, any one can access all commands through sudo su. How can i set for a particular user not to access such type and also users can mount other file systems and is able to copy data to and fro in it. hows that possible for particular user not to access mounted fie systems?

The sudo command is controlled with /etc/sudoers. I can't explain how it works exactly because I haven't learned enough about it to make any changes without having the manuals sitting next to me.

Keep in mind that if you remove sudo power from user dsl, you *might* have problems with some GUI tools that use sudo.

I haven't done any research with DSL, but it sounds as tho all users are being added to the wheel group. Any user in the wheel group can use sudo at will. try removing the users from the wheel group first, can save you lots of time mucking about in the sudoers file.
