RE: [p2-dev] p2 installer tool - unexpected IUs uninstallation

The director application is a good idea but the problem is one cannot do headless update with it (unless customizing the profile change request), like mentioned here: http://dev.eclipse.org/newslists/news.eclipse.technology.equinox/msg04742.html.  
We are checking for eclipse provisioning tool, that would be used also by the end user, thus we don't mind having a UI. We are looking for something like the P2 UI (help->"check for updates"/"install new software").  Is there a standalone version of it? Can it provision another profile except itself (our product doesn't contain the P2 bundles and is provisioned externally)?

This is because this examplary installer is meant to only install one product.
If you don't need a UI, then you can use the director application:

[p2-dev] p2 installer tool - unexpected IUs uninstallation


We encountered the following issue with the equinox p2 installer tool (http://download.eclipse.org/equinox/drops/R-3.5.1-200909170800/download.php?dropFile=equinox.p2.installer-3.5.1-win32.win32.x86.zip). Having a repositories Repo1 and Repo2 that have no common IUs:
1) Create an installation by running the installer pointing to Repo1
2) then switch to Repo2 hoping to add more stuff. However after running the installer we found out the existing stuff (from Repo1) got uninstalled.

Is this the expected behavior? May be there would be more useful and more intuitive to just add the new stuff to the already existing IUs instead of uninstalling the existing stuff. In the same way like the P2 UI in help->"check for updates"/"install new software"

Looking at the generated ProfileChangeRequest (in the code) - all the existing IUs are set for removal, and the new ones set for addition.
