 I can look up Redmine issues with 'illumos <issue>', 'issue <issue>' or '#<issue>'
-For Joyent/SmartOS issues, use the issue type and number together, e.g. OS-1234.
+For SmartOS issues, use the issue type and number together, e.g. OS-1234.
 I can also find IPDs - 'IPD123', 'IPD-123' or 'IPD 123'
 as well as OpenSolaris issues with a seven digit bug ID. If you want me to, I can also
