Revert "makechrootpkg: Avoid having code floating around outside of a function."
This reverts commit 49088b0860276c664933c2b3e36a2fef714b7a07. The fundamental intention was flawed and broken, it caused annoying issues and regressions, and the self-avowed sole purpose of the change was so that a downstream project could *post-modify the script and source it as a library*. That is not okay. You don't wrap non-factorable code in a function called main() and call it a library. The only possible use for this is to treat makechrootpkg *internals* as a library, which is not supported. Downstream projects that wish to use the functionality of makechrootpkg should treat makepkg as a command with a public API in the form of command line options. That is kind of how commands of all kinds work, since forever. That is how all users of makechrootpkg *except for parabola* use it. Arguments that "it saves us the cost of fork+exec to bash" are simply invalid. Signed-off-by: Eli Schwartz <eschwartz@archlinux.org> Signed-off-by: Levente Polyak <anthraxx@archlinux.org>
