It's not clear if this is a bad behavior or not, but when you install or uninstall crane 0.2.2-0.2 you will get additional surprising output:

restorecon reset /var/lib/crane context system_u:object_r:var_lib_t:s0->system_u:object_r:httpd_sys_content_t:s0
restorecon reset /var/lib/crane/metadata context system_u:object_r:var_lib_t:s0->system_u:object_r:httpd_sys_content_t:s0

These statements come from the crane spec file [0]. Dan Walsh originally created this policy so he should be contacted to ask two things:

1) Should we silence these outputs?
2) How would we silence these outputs?
