Some questions about "root" and "olpc" logins.

[Ajay Garg]

Hi all.

I just compared the "root" and "olpc" logins functioning on os883.img, and
my F14 laptop; and I am curious about the following things ::

a.
Why is "root" login not protected by a password on os883.img ?

b.
If I add  password for "root"; and both "root" and "olpc" are part of
"wheel" group, then :

   (i)  on os883.img, doing "su -" from "olpc" login DOES NOT ask for the
"root" password.
   (ii) on my F14 machine, doing "su -" from "olpc" login DOES ask for the
"root" password, and authentication is successful upon entering the correct
root-password.

What is the reason for this difference in behaviour?

c.
If I add password for "root", and only "root" is part of the "wheel" group,
then :

   (i)  on os883.img, doing "su -" from "olpc" login DOES ask the
root-password, but the authentication is NEVER successful, no matter what
password is entered.
   (ii) on my F14 machine, doing "su -" from "olpc" login DOES ask for the
"root" password, and authentication is successful upon entering the correct
root-password.

What is the reason for this difference in behaviour?



It might very well be a design decision; just my bad that I am unaware of
it :|


Looking forward to a reply.


Regards,
Ajay
