# @brief Applies the Endlessh configuration and starts the service on Linux systems
# @description
#     Endlessh is a endless SSH tarpit that slowly shows an infinitely long SSH welcome banner on the default
#     SSH port. It is intended to break unsophisticated malware that targets SSH.
#
#     If the `endlessh` program is installed, this script applies the configuration stored in `home/private_dot_ssh/endlessh/config.tmpl`
#     (that unpacks with Chezmoi to `~/.ssh/endlessh/config`) to the system location and then starts the service.
#
#     **Note:** _This script runs under the assumption that the actual SSH port which is defined in `home/.chezmoidata.yaml`
#     is assigned to a non-standard port like 2214. This allows the default port to be used for `endlessh`._
