For now each exec host needs an entry on it's own, and changing some attached complex_values
means a loop across all the involved nodes. Having some kind of cluster-host in the way like now
cluster-queues are present in 6.0, would make administration a lot easier.

Each cluster-host would need a definition of the attached exec hosts (or hostgroups) and each exec
host has to be attached to exactly one cluster-host. This way the current behavior could simply be
implemented by attaching only one exec host to one cluster host (similar to cluster-queues).

The commands qconf -ae,-de would be like qconf -as,-ds only to make the exec host known to SGE.

The cluster-host definition could include definitions like:

complex_values  virtual_free=2G,[@bigones=virtual_free=4G]

which is similar to cluster-queues. Possibly the qconf -aconf,... stuff may also be included here.

To put the configuration also in this entry, a new special value "INHERIT" might be useful, which allows to
keep the global configuration for this parameter. E.g.:

mailer inherit,[@custom_ones=/opt/mail]

   ------- Additional comments from reuti Thu Oct 9 03:09:32 -0700 2008 -------
Instead of having this special entry 'inherit', one and only one configuration might be more straight
forward. Entries without a host/hostgroup are global ones. Others are just for the mentioned
