"Strange Days Have Found Us" - Jim Morrison. Why, just recently I was involved in a thread that asked if it would be reasonable to ask yum to tell us what depends on package X. Is that what we need here? I was thinking of posting a request for that enhancement to Yum. It should be simple to implement, based on the following, which might be useful to the OP here. The only reply was negative, sort of. If you pick a package to remove, yum will produce a list of all the things that will be removed with it due to dependencies. When it's done, you may reply "Yes" remove that stuff or "No", don't do so. This is exactly what we need from Yum in a new feature that protects us from the accidental erroneous entry of "Yes". Same code, cut off at the knees so that removal can never actually occur. Regardless, the OP might make use of this. All OP has to do is remember to ... "JUST SAY NO!" *every* time. I was doing this and almost hit enter after typing "Y". It would have been a catastrophe. > > Sam > HTH -- Bill
