…ut content, dependencies, and UPI (unique patch ID) differ. These patches have to be rolled back in advance of applying the PSU/RU and must afterwards be installed with the correct version (=UPI). They should however not be rolled back if they are already there with the desired UPI. This helps to write more idempotent playbooks.

So there is a new parameter exclude_upi that is evaluated only if state=absent.

To keep changes in working code at a minimum the check for UPI could be acquired only by another "opatch lspatches" that costs some seconds.

Oracle_opatch searches the running listener with:

```ps -elf | grep "[0-9] $ORACLE_HOME/bin/tnslsnr"```

...then splits the line by spaces and takes the last but one field.
This does not work for a "ps -ef" result like this:

```0 S oracle   16921     1  0  80   0 - 43851 ep_pol 21:58 ?        00:00:00 /u01/app/oracle/product/12.1.0.2/ee/bin/tnslsnr LISTENER /dev/null -inherit```

In this case "linelist[-2]" deliveres "/dev/null" instead of the LISTENER
name. My fix is to search the ps line for the listener executable and use
the next field.

(I should have tested more thoroughly after the last refactoring.)
