Well. I have the NFS/SSH stuff sort of running now. I had to tune the  
boot-java scripts. And /data/openjdk7 is my NFS exported dir.
If I build with this:
export JAVA_BOOTHOST=192.168.1.33
export JAVA_BOOTDIR=/usr/local/openjdk6
export ALT_BOOTDIR=/data/boot-java

export ANT_HOME=/data/openjdk7/apache-ant-1.8.2
export ALT_FREETYPE_HEADERS_PATH=/usr/local/include
export ALT_FREETYPE_LIB_PATH=/usr/local/lib
export ALT_CUPS_HEADERS_PATH=/usr/local/include
export NO_DOCS=true
export ZERO_BUILD=true
export BUILD_CORBA=false
export BUILD_JAXP=false
export BUILD_JAXWS=false

gmake

It enters building the hotspot for zero, but then gives me the task to go  
back to my C courses. :-)

There is this error about the command-line. It is about the empty -D  
option, but I don't know where is comes from. And is it ok to ignore the  
warning? Of should they always be seen as errors while compiling java. I  
don't know how strict the java project is about this.

Any thoughts or helpful hints?

Ronald.
