How to restore backup correctly?

I forgot to setup options using 'cp', so all permissions and ownership of made backup are default. I copied the next directories:

• /etc
• /bin
• /home
• /lib
• /opt
• /sbin
• /usr
• /var

I am using Fedora 13. So, how can I restore correctly previous directories to my current reinstalled system, what permissions and ownership should this directories and files to be? My default account is 'master'. Also I want to see copied program icons in Gnome menu but they are empty.

From serverfault purple

• rpm -a --setperms --setugids will handle the system directories. You're on your own for /home and /srv.

  Also, rsync -a.

  purple : Thanks, and also there will be f.e. /etc/passwd permitted successfully? I mean is this will set perms and etc to ALL files in system directories? And how can I update programs icons?

  Ignacio Vazquez-Abrams : It will reset all permissions and ownership on all entries in the rpmdb. The icons should come back once all your permissions are correct.

  purple : Ok it works, also I fixed some problems with perms of auditd config files and some another services. But now I have another problem - after starting login window dont show available users and I can't change keyboard layout, what maybe the problem?
