Description of problem:
In RHEL 6.5 when using yum to install RPM, which in it's post section exits with 1 - yum itself returns 0. In RHEL 5.9 in such case yum returned 1.

Version-Release number of selected component (if applicable):
For 5.9 use case it worked as expected with yum 3.2.22
For 6.5 use case it does work same way with yum 3.2.29


How reproducible:


Steps to Reproduce:
1. Prepare simple RPM and call it TestRPM, which would have such in it's RPM spec post section:

#-------------------------------------------------------------------------------------------------------------
#The post macro is for running anything after the install
#-------------------------------------------------------------------------------------------------------------
%post
echo "Exiting with 1"
exit 1

2. Prepare bash testyum.sh script with such in it:
yum -y install /home/scdevops/TestRPM.x86_64.rpm
RC=$?
echo "result code: $RC"

3. Run testyum.sh on both RHEL 5.9 and 6.4

4. Observe that on 5.9 output will have such part:
...
Exiting with 1
warning: %post(TestRPM-1.0-20140529.x86_64) scriptlet failed, exit status 1
  Verifying  : TestRPM-1.0-20140529.x86_64                                                                                                                  1/1

Installed:
  TestRPM.x86_64 0:1.0-20140529

Complete!
result code: 1

i.e. result code here as expected 1

5. Observe that on 6.5 output will have such part:
...
Exiting with 1
warning: %post(TestRPM-1.0-20140529.x86_64) scriptlet failed, exit status 1
  Verifying  : TestRPM-1.0-20140529.x86_64                                                                                                                  1/1

Installed:
  TestRPM.x86_64 0:1.0-20140529

Complete!
result code: 0

i.e. result code here unexpected to be 0




Actual results:


Expected results:

Expected to behave the same way on both RHEL 5.9 and RHEL 6.5
