Описание (Description)
portablectl
may be used to attach, detach or inspect portable
service images. It's primarily a command interfacing with
systemd-portabled.service(8).
Portable service images contain an OS file system tree along with
systemd(1) unit file information. A service image may be
"attached" to the local system. If attached, a set of unit files
are copied from the image to the host, and extended with
RootDirectory= or RootImage= assignments (in case of service
units) pointing to the image file or directory, ensuring the
services will run within the file system context of the image.
Portable service images are an efficient way to bundle multiple
related services and other units together, and transfer them as a
whole between systems. When these images are attached the local
system the contained units may run in most ways like regular
system-provided units, either with full privileges or inside
strict sandboxing, depending on the selected configuration.
Specifically portable service images may be of the following
kind:
• Directory trees containing an OS, including the top-level
directories /usr/, /etc/, and so on.
• btrfs subvolumes containing OS trees, similar to normal
directory trees.
• Binary "raw" disk images containing MBR or GPT partition
tables and Linux file system partitions. (These must be
regular files, with the .raw suffix.)
