Many apt and pip commands are called inside chroot during SONiC build process. Though they are not interactive, they generate a lot of scrolling output in the console that slows down the whole SONiC installation process. https://shallowsky.com/blog/linux/performance-of-scrolling-output.html Most of this output has no added value and makes troubleshooting more complex. It can be safely disabled by setting the right environment variables and/or options. Note they cannot completely prevent underlying calls to dpkg from displaying a few output. Only a redirection to /dev/null can prevent the dpdk output from being displayed Also since there are several wrappers to apt (apt-get/apt/aptitude) and since almost all of these apt calls are done inside chroot, it is preferable from a maintenance and efficiency perspective to - create a shell function with all these parameters to install packages - cascade contiguous chroot and apt or pip commands to avoid mutiple context allocations Signed-off-by: Guillaume Lambert <guillaume.lambert@orange.com>
