Peopletools 8.49.00 and PIA

Usually, I install the Weblogic software with a separate user account than Peoplesoft.
And I manage the webserver with the user which installed Weblogic. Until now, that worked fine.
But...

A test of a Peopletools 8.49 (non-patched) show strange error when I installed the PIA installer.
My installation is on OEL4.6, I installed successfully the Peopletools 8.49 and HRMS9.0. I created an Application server and it is running.
Here below, the installation of PIA within the weblogic user (which in psoft group and has all the rights against the PS_HOME directory), I only print the end of installation :

Interesting :-(

The workaround is to invoke the $PS_HOME/psconfig.sh before running the installation, without forgot to give the rights as weel to the weblogic user (rwx against the PS_HOME directory). Then you'll be able to install the PIA as well with the weblogic user. However, still the sad warning.

Note, despite the warning, the webserver run fine, and the front end application is running as well.

Well, fortunately the problem disapear after installing the Peopletools patch 8.49.08, it doesn't required anymore to invoke the $PS_HOME/psconfig.sh, and the warning doesn't come neither. But there is some reason here above to be afraid.
The conclusion is really to avoid the first output of any release and wait for patches before going on...
