It seems to me that the main use of nsswitch.conf could be handled with
a lot less bulk and bloat by something similar to Irix's `hostresorder'
directive. A line of the form `hostresorder service1 sevice2 ...' in
/etc/resolv.conf can be used to specify the order in which services
will be consulted (and which will be consulted at all). For example,
`hostresorder local bind' says check /etc/hosts, then DNS, but skip
yp alltogether. It is also possible, using a '/' after a server name
to indicate that a service is authoritative, and further services should
only be consulted if the service was down. (Not if it couldn't resolve
the address). hostresorder may also be overridden by the env. variable
HOSTRESORDER, although I'm not as convinced that this is desirable...
