Can you run "aptitude why hal" to see which other package pulled in hal?

Unfortunately we can't just yet get rid of hal, because Xorg on kfreebsd
still requires it. There are also a few stragglers on Linux, but the
list is very short [1].

What we can possibly do is
a/ Remove hal on linux. Tools like aptitude should then list the hal
package under "Obsolete and Locally Created Packages".
Building for non-Linux only is a bit tricky though, since myself I only
use Linux.
b/ Move hal to Section oldlibs
c/ Add Breaks: hal to udev so it is automatically uninstalled on Linux.
Since hal on Linux is no longer really functional and actually broken by
that udev change, this might be the right thing to do.

I'm usuallly a bit wary with adding Breaks since they have the tendency
to confuse apt on dist-upgrades.

I've CCed the pkg-systemd maintainers list since I'd like some input
from the other systemd/udev maintainers on this.


Cheers,
Michael
