With ROOT set to a place other than "/", users, groups and cracklib file aren't created inside $ROOT after a emerge system -ave.
This happens with normal and binary packages installations to $ROOT.
Steps to Reproduce:
1.ROOT=/TEST emerge avahi cracklib
No users/groups exist, nor the cracklib file
All binary files of the package and the emerge time created users and groups should be inside $ROOT.
