I had an opportunity to experiment some more unfortunately it still isn't working but I can provide more details.
I was pointed to some documentation at https://github.com/snapcore/snapd/wiki/Content-Interface and used that to update a bit of naming in the config. I have been running on yakety with the version of snapd and other tools from yakety but in my debugging I updated to the latest snapd from the snappy edge ppa because I discovered that without that $SNAP* prefixes in the config don't work otherwise. I'm working with the promreg charm which is the producer, it has this config: slots: content: content: promreg read: [$SNAP_COMMON/promreg] The consumer is the prometheus charm which has this config. plugs: content: content: promreg target: etc/prometheus/promreg After creating the charms and installing them then linking with the command `snap connect prometheus:content promreg:content` I ran `sudo snap run --shell prometheus` initially I would get path errors, which I solved with the upgraded snapd. The directory '/var/snap/promreg/common/promreg' does exist and has data in it. The destination directory in the prometheus snap didn't originally exist but I tried creating it after reading http://askubuntu.com/questions/841004/cannot-get-basic-content-interface-example-working-with-snapcraft After getting a shell with the command `sudo snap run --shell prometheus` I see that the destination dir is empty if the destination dir was pre-existing and it doesn't exist at all if dir wasn't pre-existing. Any details I am missing? other debug steps?
