    What do you mean by "pre-installed" precisely?

    I mean, portable services can be dropped into /usr/lib/portables/,
    i.e. a dir that typically is included in the base OS image? (As
    opposed to /var/lib/portables/, where they are usually dropped, given
    they should be able to be added anytime).

    Or do you mean that they are also "pre-attached" and "pre-enabled"? If
    you want that you could either call "portablectl attach" at boot, or
    just package the symlinks/files the call creates.

This. 

Seems like 20-portable.conf is created not symbol linked. If we package the files ourself, then we need to make sure they are up to date as new versions of systemd might tweak them. I guess. 

    We could also add some special dirs that may contain images we'll
    automatically attach + enable during boot as we discover them. That'd
    be a new feature though.

Cool! If the feature is not there by the time we put our hands on portable services, we would send a patch upstream. 

Thanks for your feedback.
