Calamares is a distribution-independent system installer, with an
advanced partitioning feature for both manual and automated
partitioning operations. It is the first installer with an automated
“Replace Partition” option, which makes it easy to reuse a partition
over and over for distribution testing. Calamares is designed to be
customizable by distribution maintainers without need for cumbersome
patching, thanks to third party branding and external modules support.
