In a presentation from 2010 RedHat Summit, I saw Satellite registration (rhnreg_ks) done in a %pre stanza, while RedHat's current docs (as well as this answer) do it in %post. Registering in %post worked for me, but then I have to run yum install there to get packages from child channels, instead of keeping everything in %packages.
Trying to replicate the code for registering in %pre from that presentation (see pages 149-153) fails with no errors reported (even with --erroronfail) or pre-logs generated -- but the host is definitely not subscribed because the packages from the activation's child channel are reported missing during the %packages phase.
Has anyone succeeded in this?
