Maybe I mis-read the wiki then.While there is a lot of good documentation, it's not quite enough to teach yourself without help.

No need to test it, as it clearly wouldn't work, but the OP was worried about accidentally hitting 'y' so I'm assuming he doesn't have 'assumeyes' set. poc -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines

You should include in your dependencies all the things you directly require and not worry about redundancy. You should not assume that you don't need to require Package-B because you also require Package-A, and Package-A requires Package-B. Those dependencies can change. Let's say that one day Package-B gets split into Package-B and Package-B-libs, and Package-A now just requires Package-B-libs. If your actual need is for Package-B, you would get a run-time failure if Package-B was not installed. -- Bob Nichols "NOSPAM" is really part of my email address.

Hmmm I could wrap that in my own shell script to make it more memorable. Something like "depcheck" or the like.

Obviously. I was just trying to find a method that's failsafe. One could argue that it's very easy to accidentally add -y or press y at the prompt because that's what you're used to doing.

For instance, the package relies on mlt and mlt-python. I don't have to include mlt because mlt-python already requires it. yum erase just doesn't seem like a very elegant solution...
