I have a large number of hosts here with hyphens in their hostname, and
they all install with FAI just fine. I am even using the implicit
host-name classes for some hosts, but admittedly not with cfengine. But
there are cfengine scripts with other class names that run just fine on
If there really is a potential problem, converting hyphen to underscore
in implicit classes derived from hostnames is probably the best idea.
Underscores are not allowed in hostnames, so there can be no collision
with another host named 'eddie_vm'. I could live with that.
