1. now if i took a back up for /etc/passwd and /etc/shadow , like simple copy .. and Install a new system , and paste those two files to the new system ... are the passwords and user info. going to work ?? is it posibble ?

Mou
No, it will not generally work. Each user entry in the password file has a directory and the directories will not (likely) exist nor will the permissions match the user and group IDs, etc. (major problem) Nor will the 'dot files' exist that users need (minor problem, but can be annoying to users).

Don't forget, the login shells must match, etc. (could be major problem)

pwconv(1M)						  System Administration Commands						pwconv(1M)

NAME
pwconv - installs and updates /etc/shadow with information from /etc/passwd SYNOPSIS
pwconv DESCRIPTION
The pwconv command creates and updates /etc/shadow with information from /etc/passwd. pwconv relies on a special value of 'x' in the password field of /etc/passwd. This value of 'x' indicates that the password for the user is already in /etc/shadow and should not be modified. If the /etc/shadow file does not exist, this command will create /etc/shadow with information from /etc/passwd. The command populates /etc/shadow with the user's login name, password, and password aging information. If password aging information does not exist in /etc/passwd for a given user, none will be added to /etc/shadow. However, the last changed information will always be updated. If the /etc/shadow file does exist, the following tasks will be performed: Entries that are in the /etc/passwd file and not in the /etc/shadow file will be added to the /etc/shadow file. Entries that are in the /etc/shadow file and not in the /etc/passwd file will be removed from /etc/shadow. Password attributes (for example, password and aging information) that exist in an /etc/passwd entry will be moved to the corre- sponding entry in /etc/shadow. The pwconv command can only be used by the super-user. FILES
/etc/opasswd /etc/oshadow /etc/passwd /etc/shadow ATTRIBUTES
