Hi Daichi, I wonder which clause/aspect of the license is a problem? We've been distributing dtrace as part of our source since FreeBSD 7.1 so the terms of license must have been acceptable for inclusion in our tree & redistribution in source for each release since. I've been reading the CCDL license just now & clause 3.5 on Distribution of executable vesions states You may distribute the Executable form of the Covered Software under the terms of this License or under the terms of a license of Your choice, which may contain terms different from this License, provided that You are in compliance with the terms of this License and that the license for the Executable form does not attempt to limit or alter the recipient’s rights in the Source Code form from the rights set forth in this License. If You distribute the Covered Software in Executable form under a different license, You must make it absolutely clear that any terms which differ from this License are offered by You alone, not by the Initial Developer or Contributor. You hereby agree to indemnify the Initial Developer and every Contributor for any liability incurred by the Initial Developer or such Contributor as a result of any such terms You offer. This shouldn't pose any legal problems for the project if DTrace was redistributed in binary form should it? > Addition from my experiences, some applicaions can not be > built on DTrace/UserlandDTrace-enabled system (VBox is) and > Userland dtrace is still unstable. I see, was the virtual box issue recently, I'm pretty sure I was able to build virtual box on a DTrace enabled system in the past couple of months. Sevan
