Re: 2.1.19p1 misidentifies if server is VMWare ESX

[Mark Burgess]

Ok - the approach I am setting on for now is to look for a
directory /etc/vmware. If this is found, look at /etc/issue and convert
the string contents to a classname. Anyone can then alias this long name
themselves with with own class.

Would someone please test this. I think this is the only generic way of
doing it - otherwise we'll need a different rule for each type.
