ISSUE SUMMARY
Server-side execution of JavaScript can't be disabled via a YAML configuration file, as the noscripting option is not properly recognized.

USER IMPACT
mongod does not run when the noscripting option is used in a YAML format configuration file. When the option is removed from the file, mongod runs with server-side JavaScript execution enabled.

WORKAROUNDS
Pass the --noscripting option, or revert to a 2.4 configuration file format

AFFECTED VERSIONS
MongoDB production releases 2.6.0 and 2.6.1 are affected by this issue.

FIX VERSION
The fix is included in the 2.6.2 production release.

RESOLUTION DETAILS
The noscripting option is now recognized when used in the YAML configuration file.
