For the sake of a couple of extra pennies spent, why not give them their own DVD of the system then they can re-install if it goes pear shaped.
They indeed will receive a DVD. For emergencies. These people do not have the technical savvy to reinstall --- that is why they hire us to install the software.
If they clobber their system they will call us. We will be providing a copy of the Live DVD partly as a means to help them walk through emergency issues and partly to encourage trust. That is, giving them a copy of the DVD indicates the software really is free.
The point of having wanted to download the 32-bit packages from a 64-bit system is I have not yet built a 32-bit version. One way or another the 32-bit packages have to be downloaded at least once at our end. I can download them when I build the 32-bit version. I was just trying to save a little time and I thought the question was a nice technical curiousity.
Eventually, after a few installs and we become comfortable with the process, we will be using partition images to perform the initial installations at our end. The images will include our tweaks. Installing that way will be more efficient.
are you really going down their road as well?
I don't know where you got that idea.
The question was about working efficiently at our end, not to create vendor lock in.
