Multiple packages question

Hi all,

I have a problem that's beyond my limited RPM knowledge and need some
advice.

I have a source tree for software that runs on a small cluster. There
are several different node types, and each type requires different
software. The idea is to create one binary RPM per node type, then use
the cluster tools to distribute and install the RPMs to their correct
nodes.

My 'make install' target creates a directory structure as follows:

$INSTALL_ROOT/node1/etc/...
$INSTALL_ROOT/node1/bin/...
$INSTALL_ROOT/node1/opt/...
$INSTALL_ROOT/node2/etc/...
$INSTALL_ROOT/node1/bin/...
$INSTALL_ROOT/node2/opt/...
$INSTALL_ROOT/node3/etc/...
$INSTALL_ROOT/node1/bin/...
$INSTALL_ROOT/node3/opt/...

My spec file looks something like this (some parts omitted):

Summary: Cluster software
Name: cluster
Version: 1
Release: 1

---snip---

%package node1
Summary: Cluster software for node 1
%description
Software for node 1

%package node2
Summary: Cluster software for node 2
%description
Software for node 2

%package node3
Summary: Cluster software for node 3
%description
Software for node 3

---snip---

%install
make install INSTALL_ROOT=$RPM_BUILD_ROOT

%files node1
%defattr(-,root,root)
/node1/*

%files node2
%defattr(-,root,root)
/node2/*

%files node3
%defattr(-,root,root)
/node3/*

The problem is the files in the binary packages obviously have /node1,
node2/, etc prefixes. Is there a way to strip these off so the packages
install as intended? I might be going about this the wrong way... if
so, I'd really appreciate suggestions.

Thanks in advance,
Jim
