I've tried few days ago the opensource for the Cube 3 under RH 9.0 and it works quite nicely... the only problem is that you cannot use standard PKG files to install additional software... it says that the software has not been designed to work with this appliance... So, I guess, the only way to add additional packages is to install RPMs... anyone has any further feedback?
The install script does a check for a file called /etc/build that contains info about what type of machine it is. 4100 is RaQ 4, etc. I know there was a list of numbers posted to the list in the past... if the archives don't have it, I'll see if I can dig it out someplace.
So you could "fake" it by making that file with the right info for the box you're supposed to be, or else the PKG files have to be re-rolled to remove that dependency check in the upgrade_me script that does the actual RPM installation, etc.
