I have an rpm for which I need to change the preinstal scriptlet for testing.

However, I do not have the SRPM from which is was built.

Is it possible to change the scriptlet and/or rebuild the rpm without having the SRPM?

If so, how?

I've tried using Midnight Commander (mc) to open the rpm as a directory structure and edit the contents, but even with 444 permissions, it won't let me save any changes.
