The man page to sudo is very informative on that ;)
With sudo, you can make groups of people and / or of certain commands and specify
which people are allowed to use which
commands - with or without typing in their own password.
Example: I allowed the user britta to issue "make" anywhere with root permissions, but
I have to enter my own password.
I also allowed that user to do shutdown without being asked for the
password.
That's on my box at home that only I use, so it's ok. Other people might
not want to do it!
So, sudo is actually a way to allow people certain admin things without actually
telling them the root password (or, in my case,
without having to do a "su " before turning off my box).
There is actually a special wrapper around vi (visud) that first verifies the file for
errors - so it apperars to be safe enough.
HTH,
Britta
