Verify uid/gid on files, directories and symlinks Just output a msg when user/group is removed with no files json-parsing: Add functions for strictly dealing with ints passwd/json: Add simple scripts to convert passwd/group files to json data docs: Check-passwd/groups and ignore-remove-users/groups JSON config. entries

* `check-passwd`: Object, optional: Checks to run against the new passwd file
|

before accepting the tree. All the entries specified should exist (unless

ignored) and have the same values or the compose will fail. There are four
|

types: none (for no checking), previous (to check against the passwd file in
|
||||
the previous commit), file (to check against another passwd file), and data
|
||||
to specify the relevant passwd data in the json itself.

Example: `check-passwd: { "type": "none" }`
|

Example: `check-passwd: { "type": "previous" }`

Example: `check-passwd: { "type": "file", "filename": "local-passwd" }`
