Hello, I'm new to CentOS and looking for any useful instructions/documentation to read up on. I would like to learn about how the rootfs has been generated for CentOS. The Alternative Architecture Centos SIG already prepared a tar archive containing a CentOS 7 userland for ARM64 server boards: curl -sSL -o CentOS-7-aarch64-rootfs-7.3.1611.tar.xz http://mirror.centos.org/altarch/7/isos/aarch64 Could someone provide instructions on the steps take to build this exact image? Thanks, Scott
