This saves ~50Mb for vyos-build image: 2.04Gb -> 1.99Gb And ~19Mb for vyos image: 155Mb -> 136Mb Docker stores all files created in each layer so command ``` RUN wget -O /tmp/open-vmdk-master.zip https://github.com/.../master.zip && \ unzip -d /tmp/ /tmp/open-vmdk-master.zip && \ cd /tmp/open-vmdk-master/ && make && make install ``` will store open-vmdk-master.zip and /tmp/open-vmdk-master in the image even though there is a cleanup command later: ``` RUN rm -rf /tmp/* ``` The cleanup command just makes these files invisible in last layer. So temporary file must be removed in same RUN command not to be stored in the image. This commit adds such removals.
