What is the /etc/passwd file used for?
/etc/passwd is the file that hold the user names and passwords for all TINI users. By default there are two accounts: "root" with a password of "tini", and "guest" with a password of "guest". You may modify the contents of this file by hand, or by using the passwd command in slush. Slush also provides the useradd and userdel commands to add and remove password file entries.
