I wasn't trying to 'glorify' my lack of knowledge, I readily admit it cuz 
everytime I get rpm figured out so it will build from a src package, the API 
changes with the next version of this hat.

However, this conversation demos that everyone has their own favorite sacred 
cow.  Yumex/yum/rpm is a good tool indeed when it works.  Emphasis on "when it 
works", which since f2's foibles, seems to be worked out pretty well now days.  
I presume the acid test would be for me to install your 2.6.0p2 and see if it 
works tonight, using my existing configuration.

But obviously it won't just install and run, since an su amanda -c "amcheck 
Daily" after the install reports no problems, and used version 
2.6.2alpha-20090505.  So I had yumex remove it.

And removing it did screw things up.  It removed my /etc/xinetd.d/amanda 
config file.  Fixed, courtesy of amanda the hard way, bare metal recover to 
/tmp using dd, then copy it back & fix the perms since bare metal methods give 
the file to root.

You may want to file a bug, the config files really should not be touched if 
they are found to exist at install, and left untouched if there is an .rpmnew
version there.

So where does the rpm install it?  Should it not find stuff in /bin before it 
looks in /usr/bin?  And in /usr/lib before it looks in /usr/local/lib (or 
libexec).??

However, my $PATH has those locations interchanged.  I don't recall re-writing 
that in the last year+ though.  Shrug...

So no doubt you will continue to use the rpms, expounding on the many virtues 
of rpm, that which I wasn't able to test quickly via a simple install, and I 
will continue to play my early warning alarm role for amanda.

It Works For Me.
