thank you!
that and the plugins / utilities below should be taken care of and than IMHO
DNF will be a *painless* drop-in replacement, working that way and after it
has that state it could be really replace yum including respect the existing
configuration of /etc/yum.conf and /etc/yum.repos.d/ with excludes, includes
yum-utils
yum-plugin-security
yum-plugin-tsflags
yum-plugin-protectbase
yum-presto
one example of a production machine which pulls it's updates from cache-repos
only so no deltarpm and no manuals on all servers needed, that's why the
cache-repo is filled with the script below for several resons
* only one machine producing traffic on the mirrors
* 100% identical packages while otherwise one may hit a newer mirror
* the buildserver has for most packages sample-configs and autotests
* so while reduce WAN-traffic dramatically there are only tested packages
inside the whole network
that's some of the "small" things one needs to take care in production and
only the renaming of /var/cache/yum to /var/cache/dnf may produce side-effects
even with otherwise identical behavior
