You can do it inside the mock chroot cage. I do, on occasion. The
difficult is that I find myself wanting things like emacs to edit code
and patches, RCS to manage versions of my new .spec files, and
unpredictable dependencies as I wrote the code.

If necessary, I use one text window (with Alt-F2) to run "mock
--shell" and get that working shell window, and another window (with
Alt-F3) to drop other RPM's into /var/lib/mock/[whatever]/root/tmp/
