# docker-singularity-userperms
This is a test container for Singularity issue #977.
If a docker container holds a file or directory without owner write perms, and singularity build is run as a user (non-root), we must force owner write perms at extraction. If we don't do this, the file or dir in question cannot be modified at later layers, and build may fail.
**Expected Behaviour, fixed in PR #1295**
Container builds OK, and on run there is nothing listed inside /testdir.
```
