Enable root login in Fedora 10 (GNOME)

Log in as your average user, then elevate yourself to root (su -). First, make a backup of the file you’re about to edit:

# cp -a /etc/pam.d/gdm /etc/pam.d/gdm.orig

Now edit /etc/pam.d/gdm and change the line:

auth required pam_succeed_if.so user != root quiet

…to:

auth required pam_succeed_if.so user quiet

…save it, log out and now you can log back into GDM as root.

Install Linux Straight from an ISO without CD/DVD

GNU/Linux comes in many different flavours, apart from the fact that each individual distro has a new release almost every six months, if not less. Everytime we need to try the new distro, we burn the ISO image on the dvd and than install it. I came across a very good article on Linuxforu magzine. In this article , the author shares a simple trick by which you can install the new distro without burning it to a CD/DVD.

The only requirement is that you should have a pre-installed GNU/Linux system—which you already have, I assume.
