Meson is a modern build system that has seen a rise in adoption and some version of it is available in almost every platform supported. Compared to automake, meson has the following advantages: * Meson provides a significant boost to the build and configuration time by better exploiting parallelism. * Meson is subjectively considered to be better in readability. These merits alone justify experimenting with meson as a way of improving development time and ergonomics. However, there are some compromises to ensure the transition goes relatively smooth: * The system tests currently rely on various files within the source directory. Changing this requirement is a non-trivial task that can't be currently justified. Currently the last compiled build directory writes into the source tree which is in turn used by pytest. * The minimum version supported has been fixed at 0.61. Increasing this value will require choosing a baseline of distributions that can package with meson. On the contrary, there will likely be an attempt to decrease this value to ensure almost universal support for building BIND 9 with meson.
