Re: [Testbed-admins] network drivers in freebsd.newnode MFS?

The good news is that FreeBSD 7 works for everything you list below.

The bad news is that we haven't made a release that contains it.
However, if you have access to the Emulab git repository, you can get
everything that is needed.

Our current FBSD72-STD images support operation as delay nodes.  However,
we have not done any in-depth measurement of the fidelity.  This did require
some changes to the client-side Emulab setup code.

The current source tree supports setup of a FreeBSD 7.2 based boss/ops,
but only in 32-bit mode.

This you can download today:

http://www.emulab.net/downloads/tftpboot-100317.tar.gz

has frisbee, freebsd, and freebsd.newnode MFSes with 7.2 kernels.
