Re: [p2-dev] Sharing Your Shared Install Issues
|
Sami, Niels, did you had a chance to capture your requirements wrt Linux installs?
I did not see the description of what was below on http://wiki.eclipse.org/Equinox/p2/Shared_Install
From the initial description, I believe that it should not take much change to p2 to make the install of plugins through the native package manager work. That said, I'd rather be sure we have a complete description of the pb, and agrees on the solution that is suitable for the package managers.
Another thing to think about is uninstallation. Can it be assumed that the interdependencies of sets of plugins laid down by the package managers are captured in the metadata of the package. For example GMF depends on EMF and depends on GEF. If there is a package for each of these things, would the GMF package have deps on the EMF and GEF one?
