Changes to the python files under tlgtk do not trigger a rebuild of the tlmisc tarball, and thus not a rebuild of the rpm and deb packages. How to reproduce: > make server-bundle > find tlmisc/modules/thinlinc/tlgtk/ -name "*.py" -exec touch {} ; > make server-bundle During the second `make' call you will notice that the correct unpackaged server-bundle python files are updated, but no new rpm/deb packages are being built. Since the `tlgtk' files are used by tl-setup and various other components, new packages are expected to be built. On the other hand, replacing the above find call with > find tlmisc/modules/thinlinc/ -name "*.py" -exec touch \{\} \; results in new packages being built.
