nmd-md5sum-manifest/readme.md

Under clusterwide-file-manifest we should have directory tree of the form

`dir` - `K-Y-Z-M`:
- `K-Y-Z-M`/`clusterwide-manifest.nmd5`

These are the clusterwide manifests - i.e manifests that are produced by comparing the md5s of different nodes from the same cluster,
and producing 2 lists for each of those clusters:

- List 1 (matches):
md5sum:/file/path

- List 2 (diffs):
md5sum:/file/path
> Where List 1 is a list of all files that have the same path, and have the same path and md5sum across the cluster
> While list 2 is a list of the inverse of the above.

# Stages

## Stage 0 - ssh backbone for propogating stage1 across the cluster
```bash
yum install git -y
git clone https://git.adspem.com/opthq/nmd-md5sum-manifest.git
cd nmd-md5sum-manifest/stages
chmod +x *
./stage0-remote-run.sh
hsctl cmd run 'ls -la /root/manifest*'
```

## Stage 1 - Md5:filepath
 - Param 1 - base path (i.e `stage1.sh /` - would produce md5sum for everything under root)
 - Produces a file containing the md5:file on a given system
 - Excludes directories known to contain node-specific directories

## Stage 2 - Base manifest producer -
 Takes in files produced from Stage 1 across a cluster and produces an output base-manifest

## Stage 3 - Compares a stage 1 output against a known stage 2 manifest
