[Cooker] urpmi suggestion

[Adam Williamson]

Would it be possible to add an option to urpmi something along the lines
of --preserve-package-set? That is, an option to never replace packages
from one set with packages from another. To illustrate, mplayer is
currently at 0.90-0.rc2.3mdk and 0.90-0.rc2.1plf. urpmi --auto-select
wants to replace my installed plf package with the "newer" mdk package,
but I'd rather keep my mp3-encoding functionality and just upgrade when
a new plf package is available. Could this be done?
