systemd is broken on stretch when using ENV INITSYSTEM on

[bbinet]

I get the following error in balena logs:

Systemd init system enabled.

Searching resin.io forums points me to: https://forums.resin.io/t/the-failed-to-install-release-agent-bug-is-back/1810/5

It seems this bug has been fixed in debian base-images but not here in resin-rpi-raspbian, see the fix in esin-io-library/base-images repository:

• https://github.com/resin-io-library/base-images/pull/324
• https://github.com/resin-io-library/base-images/pull/342

I guess resin/rpi-raspbian:stretch should not have a VOLUME [/sys/fs/cgroup] layer (as resin/armv7hf-debian:stretch does not have this VOLUME [/sys/fs/cgroup] layer).

@bbinet, thanks a lot for your report. Fixed in https://github.com/resin-io-library/resin-rpi-raspbian/pull/76. The new images will be available soon.

I am seeing this same issue in resin/beaglebone-black-node-node:slim based images.
