Thanks, Myrna. I managed to set it on the command line and got it
working -- enough to test the autoboot feature from a directory other
than the one where the databases were located. It works in both Network
Server and embedded mode.
I think I have enough information for a writeup now and should be
posting another patch at some point. As you suggested, I won't mention
the derby.service property setting, since we don't want to expose that
and it isn't required in order to use the properties.

----------------------------------
Oops, I just read the Tuning Guide topic that says "Any property except
derby.system.home can be set by including it in the derby.properties file."
(http://db.apache.org/derby/docs/dev/tuning/ctunproper51399.html)
Hm, so do I set it on the java command line? or where?
Yes, on the java command line.
The documentation on the property itself
(http://db.apache.org/derby/docs/dev/tuning/rtunproper32066.html) does say that
the default value is the current directory. So I shouldn't have to set it
explicitly -- but the documentation says I ought to (without saying why -- or
how):
You may always set derby.system.home explicitly - but it will be
pointless in a derby.properties file, that's like putting the horse
behind the cart.
First comes the location of derby.system.home - this is "current" dir
(where "current" means, dir indicated by java system property
user.dir) unless you're passing in -Dderby.system.home=<whatever> to
change it from the default. Whatever is derby.system.home, derby will
look for a derby.properties file in that directory (although derby
will start with default settings if no derby.properties file is
present in the current - or other directory if derby.system.home was
specified).
Default
Current directory (the value of the JVM system property user.dir).
If you do not explicitly set the derby.system.home property when starting
Derby, the default is the directory in which Derby was started.
Note: You should always explicitly set the value of derby.system.home.
