Systemd Introduces "Portable Services" Functionality, Similar To Containers

Lennart is at it again, making complicated things that nobody asked for.

The past several months Lennart Poettering has been working on a "portable services" concept and that big ticket new feature has now landed in Systemd. Portable services are akin to containers but different.

[...] A portable service is ultimately just an OS tree, either inside of a directory tree, or inside a raw disk image containing a Linux file system. This tree is called the "image". It can be "attached" or "detached" from the system. When "attached" specific systemd units from the image are made available on the host system, then behaving pretty much exactly like locally installed system services. When "detached" these units are removed again from the host, leaving no artifacts around (except maybe messages they might have logged).

[...] The primary focus use-case of "portable services" is to extend the host system with encapsulated extensions, but provide almost full integration with the rest of the system, though possibly restricted by effective security knobs. This focus includes system extensions otherwise sometimes called "super-privileged containers".

    Try Void Linux. Azuma Hazuki did a review in her journal [soylentnews.org]. Void Linux arm64 also seems to work great on a Raspberry Pi; I found Void on Distrowatch looking for an arm64 non-systemd distro. I used it for about a week until I felt brave enough to give an arm64 Gentoo install a try (only arm32 is/was well supported on Gentoo).

    Are you aware of this about Void Linux?

    https://www.theregister.co.uk/2018/05/16/contributing_to_keep_small_linux_alive/ [theregister.co.uk]

    Other Void Linux developers recently took to the project's website to say they have "had no contact with [the main developer] since the end of January, and no meaningful contact for well over a year". Though that's bad, it wouldn't be the end of the world except that the main developer is the only one with the ability to manage much of Void's infrastructure, including the Void Linux GitHub account, IRC channels and domains.
