Extracted the changes that ST were asking for and included them in a new issue. One request is file category pre-defined values.

#95 Alternative paths for user friendly project organization

Holt has provided a pull request

Agree that we can’t define it too loosely.

Digital Signatures of Packs (Luis)

EF: Need to determine if the 64KB limitation will be a problem in practice (for very large chain-of-trust)

JK: Is there a simple test to determine the size?

LT: Could enforce a size limit.

JK: .pack.signed is a new extension?

LT: Did a simple filename check to avoid double-signing. Do need a smarter/more distributed way to determine if a pack is signed. This is mainly for demo purposes.

EF: Question of certificate management.

JK: If we agree on a root-of-trust, we could then have the certificate embedded in the binary or install in in the OS.

DB: Assuming after installation we have a secure environment or should we be able to check authenticity after pack installation?

LT: Every operation here is based on compressed pack format prior to install.
