postConfigure on a DataRed setup should exiting when system install prompt is answered 'n'

When doing a postConfigure install on a 3 pm combo system with Data Red feature set, first time through it completed the System Installing of all the nodes. But it failed in the Data Red setup when it tried to setup a peer to pm3. Gluster wasnt installed on pm3.

So installed gluster package on pm3 and when it got to the part in postConfigure to perform system install( which means install packages on remote nodes, I say 'n'. But postConfigure exiting with an error... It shouldn't do that... In my case, I had already perform the install of remote nodes, I should be able to skip that section this time around.

===== System Installation =====

System Configuration is complete, System Installation is the next step.
Would you like to continue with the System Installation? [y,n] > n

Must choose to install with DataRedundancy configured.
