rrdtool should know this option since 1.0.2. Please make sure that you
really use 1.0.4.

[Tobi: I thought it's possible to "use RRDs 1.0.4" but I can see no
effect (e.g. with "use RRDs 2.1.2")]

--alt-y-grid controls only how many horizontal grid lines you have.

There is a somewhat uncomplete (and undocumented) feature in the actual
14all (0.9) - it supports multiple config files. In fact it supports
giving a config file on the command line, i.e. you can call 14all with
the parameter "cfg=<config file>", e.g.

       http://mrtg-host/mrtg-path/14all.cgi?cfg=router.domain.com.cfg

The config file name can contain a full path and should if the cgi is
not in the workdir (next version will use 'workdir' for the cfg option).

The missing part: You have to create the page with a URL/link for every
config file yourself.
