The 'snap' directory is meant specifically for snapcraft, but it contains the following non-snapcraft-related paths, which is unsupported and will cause unexpected behavior:
- command-chain
- command-chain/desktop-launch
- command-chain/hooks-configure-desktop
- command-chain/snapcraft-runner
- manifest.yaml

If you must store these files within the 'snap' directory, move them to 'snap/local', which is ignored by snapcraft.
Failed to pull source: unable to determine source type of 'build'.
Check that the URL is correct or consider specifying `source-type` for this part. See `snapcraft help sources` for more information.
Run the same command again with --debug to shell into the environment if you wish to introspect this failure.

indeed due to strict confinement we can only currently support mounts under /home. We’re working on relaxing this requirement, but in the mean time you can bind-mount (symlinking won’t be enough) your workspace to $HOME and that should work fine.
