I didn't think there was any functional difference between:

rpm -e package-name

and 

yum remove package-name

Isn't yum just a front-end for the rpm system?

yum also does dependency checking/resolution.

There is a huge difference.

rpm -e will tell you that you package foo (that you want to install) is 
required by package bar, so don't install it.

Yum will resolve all the dependancies and try to remove foo and bar and 
anything else that is required to be removed if bar is removed, etc.

If you are not careful, you can get things like glibc removed with "yum 
remove".

I normally want to resolve my own deps if I remove something.  I once 
DID remove glibc from a machine with "yum remove" ... and that is NOT 
pretty to recover from :D

Even if that were completely true, it's not a good idea to mix
different commands, especially for installing or removing packages.
If you use rpm to find what you want to remove, remove it with rpm.

And - ditto to what everyone else already said.

That makes sense.  I am always very careful about reviewing the
dependency list when using yum for installing or removing packages, but
I can see how you might accidentally remove something you didn't intend
to.
