How do you determine whether or not a given wm needs gdm? Any wm can equally
well use kdm instead of gdm, so it is actually a conditional dependency ---
"if there is no other dm installed, and if there is some wm which depends on
the presence of a dm, don't uninstall it".

It's a mess, if you ask me. :-) Multiple wm's and de's, "maybe depending" on
multiple dm's that may or may not be present...

Best, :-)

Can you tell me one good reason that a dm should be a dependency of any wm?

Developers could try something similar to symbolic links. Each package
could add a dependency link. When the last link is deleted the actual
dependent package can be removed.

Well, if you intend to run a wm in runlevel 5, you do need a dm, right? The
problem in my view is that this is a many-to-many mapping, so a given wm may
depend on *either* a gdm or kdm or xdm or whatever, but not on any particular
one of them.

Although, strictly speaking, you can always boot into runlevel 3 and start
your wm from there manually, so the wm doesn't strictly depend on the presence
of a dm (and the formal answer to your question is "no"). However, most of the
people typically boot into runlevel 5, so it makes sense to have a dm whenever
you have a wm installed. For me that is a good enough reason. ;-)

Best, :-)

Not to difficult to provide. You have a dependency for a dm, and any
of the dm packages satisfy it. Like you do with a mail server now.
You could then use the alternate selection tool to select the dm you
want to use.

But you do get a dm installed that you do not use if you normally
start X from the cli.

That is a good question. If you boot to the cli, and use startx, you
do not need one. But if you make installing xdm part of installing
X, you are not using that much extra space. If you want a fancier
dm, install it.

How about this for a solution? Make a group for install that contains
the gdm and a group for remove that does not contain gdm. Then yum
would only have to know if it was doing an install or a remove to get
the right group.

Maybe a label field in the group file that yum could check. Label gdm
as install only. Then yum would know to ignore gdm when removing this
group.
