Richard Hughes: It's not a drop-in replacement

the bahvior is obviously not (or *not yet*) identical and the viewpoint
what are not often used bordercases may vary and depend on the environment
as i pointed out "yum -y remove kernel" is a regular task here after machines
are running long enough with the last recent one as cleanup

and because that and beause there are voices saying DNF will probably
replace YUM with Fedora 22 are the reason i started this thread to make
aware that this may be a critical change

someone may say: Fedora 22 is far away - not entirely true because F21
will be released most likely this summer and if the 6 months release
cycle holds F22 end 2014 or at least at the begin of 2015

so the only thing i wanted to point out is: please be careful with decisions
expierience shows if decisions happened they are not reverted, so it needs
take care *before* and if DNF replaces YUM later (F23, F24, F25) it could
be a valid option to rename it back to YUM and make a real drop-in replace
without any harm
