This is somewhat cumbersome, we want to see the error message, but the format changes enough to make this messy. We opt to change the golden to the new format, which only shows one of the arguments in its error output: the thing that cannot be overwritten. We then add a filter that rewrites the old output format with sed patterns to be exactly like the new format, so this will work everywhere again, without changing or adding filters to obscure error messages.

Introduction
scoutfs is a clustered in-kernel Linux filesystem designed to support large archival systems. It features additional interfaces and metadata so that archive agents can perform their maintenance workflows without walking all the files in the namespace. Its cluster support lets deployments add nodes to satisfy archival tier bandwidth targets.
The design goal is to reach file populations in the trillions, with the archival bandwidth to match, while remaining operational and responsive.
Highlights of the design and implementation include:
- Fully consistent POSIX semantics between nodes
- Atomic transactions to maintain consistent persistent structures
- Integrated archival metadata replaces syncing to external databases
- Dynamic seperation of resources lets nodes write in parallel
- 64bit throughout; no limits on file or directory sizes or counts
- Open GPLv2 implementation
