User Feedback :: I Just Ordered DSL
Just use the 'sudo command' to get root access eg:
sudo tex (this would run tex as root)
sudo su (would give root access at the terminal)
or just select the root terminal from the fluxbox menu
If you decide to do a hdd install, it will ask you for new passowrds on reboot of that install.
Hope this helps.
