Description:

It turns out that installing Plasma5 in /opt creates several issues: polkit authentication stuff is broken, and some users are experiencing 100% CPU usage in powerdevil due to conflicting d-bus services in /usr and /opt [1] (see also comments in [2])

In order to be able to move Plasma5 to /usr (so that it only conflicts with kdebase-worskpace), baloo needs to be split in the same way as kactivities. Attached is a proposed PKGBUILD that splits it in 3 packages:

- baloo4: runtime binaries, it conflicts with baloo5, which is a drop-in replacement for it. Both baloo4 and baloo5 provide baloo.
- baloo4-akonadi: akonadi agent, it is coinstallable with baloo5, but will conflict with the upcoming akonadi-search package (split-off from baloo5, will be a dependency of kdepim5).
- libbaloo4: libraries and headers, coinstallable with baloo5.

kdepim-libkdepim should depend on baloo4-akonadi, gwenview and baloo-widgets should depend on libbaloo4 and baloo.
