@johnnybubonic Thanks for the extensive documentation of the proper fix!

I'm leaning towards a cleaner version of "the hacky way" based on #151, because
a) decoupling formulas (selinux/openssh) reduces need for maintenance.
b) I think a simple use_check_cmd: False in osfingermap.yaml is sufficient to prevent the original bug.

Nevertheless I would add proper documentation in pillar.example on

1. how to set the flag based on grains. (use_check_cmd: {{ salt['grains.get']('selinux:enforced', False) != 'Enforcing' }})
2. how to do it properly, which will essentially be a link to this Issue.

@alxwr -

true, and agreed on all points, and it DOES reduce dependencies. sometimes KISS is best. :)
thanks for reviewing this!
