| There has been significant discussion of these sorts of

| this list for over a week now. Please review the recent list
| archive messages since test1 release.  This is not a yum
| problem.. this is a 
| problem with the development tree. The packages in the
| development 
| tree are not always self-consistent.  Yum attempts to resolve
| dependancies, but if the development tree is not fully
| self-consistent, the dependancies are unresolvable and hence
| the error message.  These are packaging errors that the Core
| package maintainers 
| need to fix by providing associated package updates to make the
| tree self-consistent.
| 
| For example libwnck in the development tree no longer provides
| libwnck-1.so.4 libwnck-2.10.0-1.i386.rpm now  provides
| libwnck-1.so.16 
| 
| Many packages in the development tree stilll require
| libwnck-1.so.4, 
| for example
| gnome-python2-libwnck-2.9.3-1.i386.rpm requires libwnck-1.so.4
| 
| Yum has the ability to exclude packages from the update
| calculation, 
| the specific --exclude options needed from day to day seems to
| be a 
| popular topic of discussion among some list members.

Thanks for the long post. I actually have read the archives
extensively, but, as I'm still fairly new to Linux, it's hard to
separate the sound suggestions from the rest. As you point out
yourself, above, the use of -y is not such a great idea, an idea I
got from this list's archive. You suggest that I do targetted
updates, but, how does one figure out the targets? The list
produced by my yum upgrade command was very long. My FC4t1 box is
up, and I was able to fix the worst problem, the gdm hogging
resources problem. I did that by turning off gpg checking in the
yum.conf file. Since I don't fully understand what the effect of
doing that was, I've turned it back on.
