Berry Linux Reviews

Hello there. It would be cool to add a program like zypper or yum into this project. I tried to use rpm but when I install the program always tell me > [root@berry-love ~]# yum bash: yum: command not found So I wonder why it do such a thing? I installed it with a hell of dependencies. [root@berry-love ~]# rpm -i -g /home/berry/Downloads/yum-3.4.3-507.fc23.noarch.rpm /home/berry/Downloads/dnf-yum-1.1.3-1.fc23.noarch.rpm /home/berry/Downloads/pygpgme-0.3-13.fc23.i686.rpm /home/berry/Downloads/pyliblzma-0.5.3-14.fc23.i686.rpm /home/berry/Downloads/python-iniparse-0.4-16.fc23.noarch.rpm /home/berry/Downloads/python-six-1.9.0-3.fc23.noarch.rpm /home/berry/Downloads/python-urlgrabber-3.10.1-7.fc23.noarch.rpm /home/berry/Downloads/python-pycurl-7.19.5.1-3.fc23.i686.rpm /home/berry/Downloads/pyxattr-0.5.3-5.fc23.i686.rpm /home/berry/Downloads/rpm-python-4.13.0-0.rc1.3.fc23.i686.rpm /home/berry/Downloads/rpm-4.13.0-0.rc1.3.fc23.i686.rpm /home/berry/Downloads/curl-7.43.0-4.fc23.i686.rpm /home/berry/Downloads/libmetalink-0.1.2-8.fc23.i686.rpm /home/berry/Downloads/yum-metadata-parser-1.1.4-15.fc23.i686.rpm Can you help me?
