postfix etc/* files are never updated...

Description of problem:
when postfix is installed, hard links and copies are created for a lot of libs
and configuration files - among these are: /var/spool/postfix/etc/localtime
then during postfix startup, the following file is copied
/etc/resolv.conf -> /var/spool/postfix/etc/resolv.conf
but this only happens if the resolv.conf file does NOT exist in the postfix /etc
dir... This means, that if your system is for instance running dhcp or you just
need to change DNS servers or options in resolv.conf, the the postfix
configuration becomes invalid.
i guess the same goes for the localtime file - i saw a problem with this one
before, where an error in the maillog said /etc/localtime is newer than
/var/spool/postfix/etc/localtime (or something like that)
the services file too??? it probably doesn't change that much but if it does(but
the means of an rpm update etc.), will the hard link still work? probably not!
I think that the resolv.conf file should be copied at server start regardless of
what's in the postfix etc dir at the time... And localtime too. I guess i'd put
the services file in there together with the two other files but i'll leave that
up to you.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. install rh 8 without entering dns servers
2. switch to postfix using redhat-switchmail
3. configure postfix to use "relayhost smtp.server.somewhere.com"
4. start postfix
5. notice that postfix can't resolve the relayhost
6. add your dns servers to /etc/resolv.conf
7. restart postfix
5. notice that postfix will still not be able to resolve the relayhost
Actual Results: the resolv.conf localtime and services file en the postfix
chrooted etc dir are not properly kept in sync with the files in /etc
Expected Results: the resolv.conf localtime and services file en the postfix
chrooted etc dir should be properly kept in sync with the files in /etc
It is not desirable that postfix etc/* contain the current system settings.
I have several installations that require this to be the case.
Perhaps a switch (probably more suited to postfix dev) to link the postfix
etc/* files exactly with the system versions?
This is similar to Bug 74129
For RHL 9 add this:

Better patch, copies files always
Note, the current postfix rpm no longer runs postfix in a chroot jail, this
alevates a lot of these types of problems.
