It's not so much a flame as an observation that package managers don't 
and can't work with uncoordinated changes in the same namespace.  And 
repotags don't do much to help unless the package manager uses them - 
although they do help in diagnosing problems after they've happened.

I'm not convinced.  I've got plenty of disk space.  If you are going to 
modify a stock library, name it something else and name the package it's 
in something else - and make the things that need your non-stock changes 
use your copy instead.  Do the same things you'd do with it if you were 
developing and testing a modified version on your own machine while 
keeping the stock version in place and running.  This also allows the 
scenario where different users on the same machine want to run packages 
from different repos.

I'm not convinced there either.  Even if you follow LSB guidelines, 
uncoordinated packagers are going to step on each others' choices in 
compile options, config file layout.

Does one or the other of the epel and rpmforge copies of viewvc violate 
lsb?  If an update flips from one to the other your setup is broken - 
and it doesn't even involve dependencies.
