freebsd-update, fetch once upgrade many machines

[Paul Schenkeveld]

Hi,

Is it possible to fetch files needed for freebsd-update once and put
them on a local fileserver to update many machines?

The reason for asking is that all these machines are on secure
networks and are not allowed to have Internet access but can all
access a common fileserver (using FTP, HTTP, SSH but not NFS).

I can safely assume that all these machines run the same version of
FreeBSD, installed from binary distributions, GENERIC kernel and only
upgraded using freebsd-update.

Thanks,

Paul Schenkeveld
