Statement on the Use of the BSD Daemon Figure:
The BSD Daemon is to be used in the context of BSD software.
So, if you are using BSD software (FreeBSD, NetBSD, OpenBSD,
or BSD utilities) in your Intranet environment, then use of the
daemon is appropriate. If you are a Microsoft or Linux shop, then it
is not appropriate.
Individuals may use the daemon for their personal use within the
bounds of good taste (an example of bad taste was a picture of the
BSD daemon blowtorching a Solaris logo). When reasonably possible,
I would like the text ``BSD Daemon Copyright 1988 by Marshall Kirk
McKusick. All Rights Reserved.'' to be included.  This text need
not be etched into the figure or garishly displayed when using the
daemon as say an Icon in a Web window. A good example of how
to handle the due credit in a web page is to create a link from
the daemon picture to the following text:
    BSD Daemon Copyright 1988 by Marshall Kirk McKusick.
     All Rights Reserved.
    Permission to use the daemon may be obtained from:
         Marshall Kirk McKusick
         1614 Oxford St
         Berkeley, CA 94709-1608
     or via email at
 If you are looking for daemon images or daemon shirts, a pictorial
 history of the daemon and daemon shirts are available at my site, If you are looking for daemon badges,
 see the site at For other
 paraphanalia, see the site at
 If you want to mass produce the daemon on Tshirts, CDROM's, or other
 products you need to request permission in advance. In general, I require
 that the daemon be used in an appropriate way. This means that it
 has to be something related to BSD and not expropriated as a company
 logo (though I do allow companies with BSD-based products such as
 FreeBSD Mall or Daemon News to use it).  I regret having to be so
 legalistic about the daemon, but I almost lost the daemon to a
 certain large company because I failed to show due diligence in
 protecting it. So, I've taken due diligence seriously since then.
