Not wanting to start a religious war, But though I think yum is
excellent, I still prefer up2date. I find myself wanting to know "what the heck that package is" and with up2date I just highlight the package. With yum on the other hand, I do a check-update, followed by an info, followed by an update, each time I need to download .repo files look at dependencies etc. etc.
yum shell
list updates info somepackage update run
all with only a single read of the repo information.
Of course since either yum or up2date gets broken from time to time,
I think it's nice to have both.
broken how? The thing that most often "breaks" yum is mirrors being out of sync or the repositories being in unresolved states. Not exactly yum's fault.
