“pacstrap” is a script included in the Arch Linux distribution that is used to install packages to a new root directory. This script is run during the initial installation process and is used to set up the base system by installing a minimal set of packages. The “pacstrap” script can also be run later to add additional packages to the system. The script takes as its argument the path to the root directory to which packages should be installed, as well as a list of packages to install. The packages specified will be downloaded and installed, along with any dependencies they have. This makes “pacstrap” a useful tool for installing a custom Arch Linux system, for example on a disk partition or in a virtual machine.
