Portable service and bind paths

[Claes H <claesatwork@xxxxxxxxx>]

Hi,
I am experimenting with a portable service for Home Assistant. I think
embedding it as a portable service would be a good way to isolate its
quite extensive dependencies.

But I would like to bind mount a directory on the host into the
service and I can't figure it out.
The portable service file looks like below but the bind path does not
seem to take effect.

Is this maybe the wrong way to go? I am able to bind mount it if I
start using a regular service, that calls systemd-nspawn (like
ExecStart=/usr/bin/systemd-nspawn -M homeassistant /srv/homeassistant/bin/hass
) and has a corresponding .nspawn file with Bind attribute.

I also read in the documentation that .nspawn files are not among the
unit fies copied out from the image. What is the recommended way to go
about with this for a portable service?

best regards,
Claes
