Can I make an rpm abort installation in a %post script?

I don't believe there is. %post is not necessarily run directly after your
package installs in cases where numerous packages are installed at once.

So if package A uninstalls in %post because of a failure, package B
requires package A, but package A's post script isn't executed until after
B is installed - that could be problematic.

Better to use Requires to make sure your RPM has everything it needs to
not fail its %post scriptlet.
