>Description:
Right after a fresh install, at the first boot into the installed system postfix prints out some warnings / errors:

postfix: warning: /etc/postfix/main.cf, line 707: overriding earlier entry: inet_protocols=all
/usr/sbin/postconf: warning: /etc/postfix/main.cf, line 707: overriding earlier entry: inet_protocols=all
/usr/sbin/postconf: warning: /etc/postfix/main.cf, line 707: overriding earlier entry: inet_protocols=all
/usr/sbin/postconf: warning: /etc/postfix/main.cf, line 707: overriding earlier entry: inet_protocols=all
/usr/libexec/postfix/post-install: Error: /etc/postfix/postfix-files is not a file.
postfix/postlog: warning: /etc/postfix/main.cf, line 707: overriding earlier entry: inet_protocols=all
postfix/postfix-script: fatal: unable to create missing queue directories

>How-To-Repeat:
n00191# postfix check
postfix: warning: /etc/postfix/main.cf, line 707: overriding earlier entry: inet_protocols=all
/usr/sbin/postconf: warning: /etc/postfix/main.cf, line 707: overriding earlier entry: inet_protocols=all
/usr/sbin/postconf: warning: /etc/postfix/main.cf, line 707: overriding earlier entry: inet_protocols=all
/usr/sbin/postconf: warning: /etc/postfix/main.cf, line 707: overriding earlier entry: inet_protocols=all
/usr/libexec/postfix/post-install: Error: /etc/postfix/postfix-files is not a file.
postfix/postlog: warning: /etc/postfix/main.cf, line 707: overriding earlier entry: inet_protocols=all
postfix/postfix-script: fatal: unable to create missing queue directories

>Fix:
comment out the following lines at the bottom of the /etc/postfix/main.cf in the installed system:

```
#meta_directory = /etc/postfix
#inet_protocols = ipv4
```

This should be fixed until the final release - even when it is likely not a major issue it might scare new users to be welcomed with a error message.
