So verylooong will be installed before veryl. OTHO. AFAICT it is possible anyway to influence
the ordering if some other package increment the incoming edge deps on the veryl package.
yum, which is based on rpmlib, do the same. Anaconda ordering is/was/can be different.

Latter is a spec file which should be used to create a package for a
local repository. Register this repository in your kickstart file, and
add 'fedora-usermgmt-my' to the %files section. Due to its shorter
name it wins against 'fedora-usermgmt-shadow-utils' (which applies the
non-predictable behaviour by default).
