[Yum-devel] problemo with new depsolver

[Terje Rosten]

When going from rawhide 2007-02-12 to 2007-02-19 with
fresh yum cvs and

$ python yummain.py update

I get:

[root at lanadu yum]# python yummain.py update

Not very clever :-)


To compare, apt-get update && apt-get dist-upgrade want to:

Which is the same the apt-get result, in less nice formatting. 

As a bonus depsolving in yum cvs was horrible slow.
