[systemd-devel] directory for machine templates

[Johannes Ernst]

/var/lib/machines is intended to be, as I understand it, for (virtual) machines that are or could be started at every boot.

Would it make sense to have a similar convention for templates?

Use cases:
1. Testing. Pull base image once, run lots of containers from the same base image
2. Hosting. Pull common base image(s) once, let customers instantiate lots of containers from the same base image(s)

It could work like this, with -T (template) in analogy to -M (machine):

$ system-nspawn -T fedora-xyz -M fedora-test123

where /var/lib/machine-templates/fedora-xyz is the file downloaded with something like:

$ machinectl pull-raw-template http://../fedora-xyz <http://../fedora-xyz>

Just a thought.

Cheers,



Johannes.
