Yum can not remove items that are needed by other programs ... it will
fail the dependency checks.

One should not remove packages (IMHO) with any GUI tool.  Heck, I don't
even remove packages with yum, but individually and from the command
line.  I could tell you about a machine where I used yum to remove a
file and it's dependencies, didn't pay attention to the file list, and
it tried to remove glibc ... and I can duplicate that same problem in
apt.  (A machine will break part of the way though removing glibc and it
is not pretty :P)

Removing packages with auto dependency resolution is dangerous (IMHO)
and should be avoided.

What do other think about this?
