Other than doing what Dan mentioned, you can define ArchGeneric and OpSysGeneric yourself, e.g.

ArchGeneric = SUN
OpSysGeneric = WINNT
STARTD_ATTRS = ArchGeneric, OpSysGeneric
LOCAL_CONFIG_FILE = $(ETC)/condor_config.$(ArchGeneric).$(OpSysGeneric), $(ETC)/$(HOSTNAME).local

This gives you ArchGeneric and OpSysGeneric attributes on all your slots, useful for Requirements expressions, and lets you specify the local config file using the same values.

It requires that you have a different global condor_config file for each ArchGeneric/OpSysGeneric combination that makes sense (I'd like to see SUN.WINNT running).

You could probably write a boot script that modified condor_config to set *Generic in some expected way.

Best,
