Guidance porting to KDE 4

Hi and thanks for your answers,

The main goal of porting Guidance to KDE 4 is not to blindly integrate
all of its sub applications to the KDE Admin. The goal is to port the
applications that do not already cover something that the KDE main
tree don't do actually.

Here is my opinion on each sub applications :

displayconfig :
You are right, the displayconfig for example don't need to be ported,
as another project already do this in KDE.

userconfig :
KUser and userconfig both look like a graphical editor for /etc/group
and /etc/passwd. In my opinion, userconfig misses only 2/3 features
that KUser has before being able to replace it. In my opinion,
userconfig could only be the start of an application that could be
improved, and it will be integrated only if KDE core developers think
it is sufficently powerful and have an interest. If the Fedora tool
has a backend and that's this backend is providen to any distribution,
then userconfig will be improved to use it. As I said previously, it's
only a start (or restart in this case, as KUser exists).

serviceconfig :
Serviceconfig has pratically the same history than userconfig, but the
main difference is that KSysV is really old and not really good, so
its replacing will be easier and earlier.

mountconfig :
If mountconfig has issues, they will need to be fixed before
integrating it to KDE Admin. I've maybe not specifying that each sub
applications will have to follow the KDE application process

wineconfig :
If a D-Bus interface has been started in the Wine project, maybe we
could wait its release to see if the porting is necessary, or if it
could be better to rewrite it from scratch.

guidance-power-manager :
It seems that power-devil will be the next application that will take
care about battery management, so, the Guidance one is not
particularly needed.

To conclude, there are 3 applications of the Guidance project that
could be used, and that could be ported to KDE 4 (userconfig port is
already started). Those applications will have to follow the KDE
application integration policy one by one, to be sure there are enough
mature to be part of KDE.

The guidance-kde4 branch will contain only those 3 applications, to
reflect what we said here.

Do you agree with this ?
