: I think the history of that might involve back compat issues.
Correct.
Tracy: the *default* location for dataDir, if you have nothing specified
in your solrconfig.xml is to be relative your Solr Home ... but if you
specify a path, that path is resolved relative the CWD.
One of the use cases for this is to have the same solr home dire used by
many instances of Solr, each with a distinct data dir (but you can just
change the working dir)
If you look ta the trunk version of solr, the example dataDir config looks
like this...
<dataDir>${solr.data.dir:}</dataDir>
...which results in a no dataDir being specified (unless you set the
solr.data.dir system property). But in the releases up to an including
1.4.1 a differnet (poorer) choice was made for the example value.

I agree, that wording is somwhat confusing -- particularly since the
config then specifies a value which will usualy be the data dir in the
default solr home dir if solr.solr.home is *not* specified -- but that
value is not the "default"
Bottom Line: if you change your solrconfig.xml to use the syntax i listed
above, it should do what you want. Alternately: you can specifiy the
solr.data.dir system property at run time, and have total control over
where the data dir is at runtime, indepndent of where the solr home dir
is.
