<li>RPM Introduction
  <ul><li>What is RPM<br> 
		<a href="http://www.rpm.org">RPM website</a></li>
  <li>Origination<br>
	Thank you, Red Hat, Pacific Hi-Tech (now TurboLinux)</li>

	By author Ed Bailey, at Red Hat.  
    <ul><li>... getting a bit dated, but the baseline book</li>
    <li>Available as a postscript file at RPM website
	... can we get a build in GenericBooks.Com ?</li>

<li>Why 
  <ul><li>Cross-platform from a single set of sources and patches</li>
  <li>Pristine sources used</li>
  <li>Version control</li>
  <li>Support load management<br>
	The end customer site can quickly be checked for compromise, or
	'tinkering' with binaries, or configuration files.  If there <i>is</i>
	a problem, it can be reliably uninstalled and reinstalled to a known
	status.</li>
  <li>Accountability<br>
	Signing, authorship, and packager information are readily available</li>
  <li>Verification and Security<br>
    <ul><li>Tripwire analogue, although can be subverted with effort</li>
    <li>... more prompt installation of security fixes ... The RedHat 
<i>intra-</i>distribution releases are almost <u>all</u> security 
related [some relate to major SNAFU's in packages, not caught in
BETA testing.]</li></ul></li>
  <li>Upgradability<br>
	Red Hat versions since 3.0.3 (ca. 1996) can be seamlessly 
	moved to the current release level.<br>
<br>
	... Our demo today<br>
	[We will build and bump several boxes]</li></ul>
<br>
	Note:  Red Hat itself, in its CD based upgrades <i>does NOT</i> honor
	the principle of not using the --force option.  This is probably in 
	the interest of avoiding support load.  Their disk based upgrade 
	procedure requires a reboot, from CD or floppy.<br>
<br>
	Owl River Company [ORC]
	technical support is the most 'vocal' advocate of 'hot box' upgrades
	on the RPM-list.  The presentation today is representative of 
	support approach of ORC, which is initially more 'expensive' in 
	terms of sysadmin time, 
	but MUCH more 'correct' to RPM design goals.  The 'payback' of 
	such an approach is that the proprietary ORC host management tools 
	will thereafter manage 'by exception' the day-to-day host task 
	supervision load in a production environment.<br>

cookbook:  (clip and save) 

to rebuild a SRPM on a local machine:


    cd /usr/src
#          (A convenient place to stash unbuilt SRPMs)
    rpm -Uvh fetchmail-5.4.4-1.src.rpm
    rpmbuild -ba /usr/src/redhat/SPECS/fetchmail{-hit TAB key-}   
#          (It builds)   
#          (Note where the result is)
    rpm -Uvh /usr/src/redhat/RPMS/i386.fetchmail-5.4.4-1.rpm
