Hi, I've read this topic : http://www.howtoforge.com/forums/showthread.php?t=41595 And I've some more question : 1) Why not copy these file to : gshadow ? 2) When I setup a new config, some of the component have a different UID… So after the replacement of group, passwd and shadow some process won't start anymore… -> is there a way to fix it ? -> or a way to make a better import / export ? Thx !
