Re: [equinox-dev] Installer and agent data location

As you mentioned earlier, the /p2 directory is not created by the installer
in the installation directory.
I also noticed that the /p2 directory is created and updated [when the
eclipse is running] in the install directory (the directory where the
installer was).
I think that the installer forget to move or, somehow, is not moving the /p2
directory to the installation directory.

1. I did not find a bug for this. Is there one to keep me on track of this?

In RC4, I noticed that the /features directory is back. The installer
delivered in the RC4 is not creating the /features directory also.

2. I did not find a bug for this. Is there one to keep me on track of this?
