Subject: RPM Packaging of the latest Snapshot
From: Bennett Todd (betrahul.net)

As the first step of working with the new content filtering
features, I wanted (naturally) to rpm the latest postfix.

I may turn up some more stuff that needs tweaking in further
testing, but I think I've got as simple and straightforward a
packaging of the latest snapshot as I can manage. It's not really as
simple as I'd ideally like. A few changes would account for most of
the ick.

It would be _way_ cleaner if we could avoid the here doc feeding the
interactive "INSTALL.sh" script; if that script could accept cmdline
args, or envars, or a config file with var=value defines, or
whatever to override a couple of defaults while still accepting the
others, that would definitely be nicer.

I had to dike out the calls to chown and chgrp in INSTALL.sh so the
resulting RPM would build as non-root, but that was only one line.

Then I had to do some manual frobbing to get spawn built, to make
and install the man page for it, and to get a symlink to sendmail
into /usr/lib/sendmail. But there's still not too much excess cruft
in this one; it's as clean as I can make it.

There are still some rough spots; if a /usr/lib/sendmail exists when
the rpm is built, the INSTALL.sh will decide to install sendmail
there rather than into /usr/sbin, and so the symlink will fail. And
I used the simplest useradd invocation to ensure that a postfix
userid is available in %pre, and made no effort to clean up in
%postun.

But if you get this note, this packaging is basically sound.

Unlike the earlier packaging I worked on, which is ... well, you
could call it "evolved", if you wanted to be kind:-) ... this one
is as close as I can manage to a direct simple straight install,
and mostly avoids non-default options. I did include LDAP and PCRE,
since they're so easy to do.

As always, when doing any non-trivial upgrade, save the non-default
options you've configured with "postconf -n >save-file", carefully
upgrade the software (I did an "rpm -e --nodeps postfix", then I
went "rm -rf /etc/postfix /var/spool/postfix", and finished by
making sure the "postfix" user and group were removed); then edit
those customizations you actually need back into main.cf, and try
starting; make sure to check maillog, and test carefully.
