That's a great explanation---thanks!

One comment to slide 22: in yum/rpm world you can also look up
files that do not exist, just like 'apt-file search'

yum whatprovides bin/wonder

I like chaining rpm commands, e.g. to find what does libwrap do, I print 
the description of a package that owns file /lib/libwrap.so

rpm -qi `rpm -qf /lib/libwrap.so.0`


Also, rpm has the --queryformat switch which is easier to use than 
greping the output of the default -qi output; e.g. to find the package 
that takes most space:

rpm -qa --queryformat '%{size} %{name} %{version}\n' | sort -n
