Good people,

I have VirtualBox image of the ClangBSD (kernel + world i386) with the
clang installed, and Niclas generously offered to host it on his FTP
server. Image size (compressed) is slightly over 1GB.

Before we go through the hoops of moving image over, I am trying to see
whether there is sufficient interest in it. Would people, who are
interested, please, contact me off list -- if count tallies at about 10,
I will upload the image and Niclas will post URL here.

While I realize that moving target like ClangBSD, probably made this
image obsolete while I was building it, I think it will provide starting
point for those who want to test and/or experiment at the cost of

Please, let me know.
