Arch Linux

Currently, core/btrfs-progs depens on python, presumably to support bindings for libbtrfsutils. However, the package doesn't contain any python-related files. This is because one needs to install the bindings with make install_python, see https://github.com/kdave/btrfs-progs/blob/master/INSTALL . On the other hand, btrfs-progs is a core package and doesn't strictly require python (the size ratio of python / btrfs-progs is ~ 26). Therefore, I suggest to move python from depends() to optdepends() (makedepends already contains python-setuptools which will pull python).

The above amount to the following change of PKGBUILD (also attached):
