Not all, but those using fail_now method:

[root@winter ~]# foreman-installer --scenario foreman --migrations-only >/dev/null
[root@winter ~]# foreman-installer --scenario foreman --migrations-only
ERROR: Selected scenario is DISABLED, can not continue.
       Use --list-scenarios to list available options.
       You can also --enable-scenario SCENARIO to make the selected scenario available.

This is bigger problem than it looks like, because we redirect STDOUT to /dev/null in RPM scriplets!
