just keep /etc/passwd. /etc/shadow and homes ;-)
STOP! What about /etc/group? And if you just copy the old passwd file, you will loose all changed system users!
Can I just copy and paste the regular users in the old /etc/passwd, /etc/shadow and /etc/group to the new one ?
Hi Jean-François,
only if you use the same method to crypt the passwords. Look in your old /etc/shadow and compare the password field to the one in the new /etc/shadow. If your old passwords use another encryption, you must change the method on 10.0 via YaST. This only works if you use "local(/etc/passwd)" for authentification.
JFYI -- passwords encrypted with different algorithms are different enough to figure out the algorithm used, and to process it correctly. Right now I have blowfish selected as a default, but still have a few users with md5-encrypted passwords. -- Best regards, Alexander.
