[Fedora-legal-list] CDDL in system library

[Florian Weimer]

libxcrypt contains some code from OpenSolaris to implement their 
password hashing.  It's licensed under the CDDL:

The rest of the library is a combination of 3-clause BSD, 2-clause BSD 
(ISC), LGPLv2+, CC0 or a public domain dedication,

Applications do not link to this code directly, but they will use it 
automatically if needed, e.g. if /etc/shadow contains passwords hashed 
in this way.

Is this a problem?  I think we could patch libxcrypt to remove support 
at run-time if necessary, with little practical impact.

Thanks,
Florian
