# Portable Services Introduction
This systemd version includes a preview of the "portable service"
concept. "Portable Services" are supposed to be an incremental improvement over
traditional system services, making two specific facets of container management
available to system services more readily. Specifically:
systemd (since version 239) supports a concept of "Portable Services".
"Portable Services" are a delivery method for system services that uses
two specific features of container management:
1. The bundling of applications, i.e. packing up multiple services, their
binaries and all their dependencies in an image, and running them
directly from it.
1. Applications are bundled. I.e. multiple services, their binaries and all
their dependencies are packaged in an image, and are run directly from it.
2. Stricter default security policies, i.e. sand-boxing of applications.
The primary tool for interfacing with "portable services" is the new
"portablectl" program. It's currently shipped in /usr/lib/systemd/portablectl
(i.e. not in the `$PATH`), since it's not yet considered part of the officially
supported systemd interfaces — it's a preview still after all.
The primary tool for interacting with Portable Services is `portablectl`,
and they are managed by the `systemd-portabled` service.
Portable services don't bring anything inherently new to the table. All they do
is put together known concepts in a slightly nicer way to cover a specific set
