Re: upgrade via rpm erase the product

Hi

As wrote on the online version of the maximum RPM book
(http://www.rpm.org/max-rpm/s1-rpm-upgrade-nearly-identical.html),
the installation scripts of the new version is do before the uninstallation
scripts of the old version.
The upgrade scenario with rpm -U command is so:
(/opt/jonas and jonas user are soon created with the first installation of the
5.2.0)
- installation of the new version 5.3.0-M2
 -- check user jonas exists ? ok (don't create)
 -- copy files on /opt/jonas
 -- clean /opt/jonas/work
 -- set JOnAS env => already make
 -- installation done !
- uninstallation scripts of the old version 5.2.0
 -- stop jonas service
 -- clean jonas root (remove all files in /opt/jonas/*) 
 -- uninstall done !
The upgrade is done but the /opt/jonas is empty!!!

The workaround is to don't use the rpm -U or rpm -F with jonas-full package. A
rpm -e jonas-full must be make before the rpm -i of the new version.

Best Regards,
