Hi,
I'm experimenting with snaps and would like to use the content interface
to share files with another snap. I couldn't find documentation for it,
so I figured I'd ask.
Since there's a "write:" option for the content interface, and the snap
itself is read-only, it seemed likely that there is a way to expose
files in $SNAP_DATA or $SNAP_COMMON so that the consuming snap could see
and modify them.
I tried using $SNAP_DATA for the path, but that doesn't work:
cannot mount /snap/supplier/x1/$SNAP_DATA at /snap/consumer/x1/data with
options bind. errmsg: No such file or directory
The mount point exists, so I believe it was using "$SNAP_DATA"
literally, and not doing any substitution. What's the right way to point
it at the right directory (assuming it's possible)?
If write is not possible, is there a way to expose $SNAP_DATA with the
"read:" option?
Thanks in advance. :)
