@ -5,6 +5,21 @@ This library for assembly and disassembly of tar archives, facilitated by
`github.com/vbatts/tar-split/tar/storage`.
Concerns
--------
For completely safe assembly/disassembly, there will need to be a CAS
directory, that maps to a checksum in the `storage.Entity` of
`storage.FileType`.
This is due to the fact that tar archives _can_ allow multiple records for the
same path, but the last one effectively wins. Even if the prior records had a
different payload.
In this way, when assembling an archive from relative paths, if the archive has
multiple entries for the same path, then all payloads read in from a relative
path would be identical.
Thoughts
--------
