Hi. I appear to have solved this by running xelatex -ini manually and then copying the ..fmt file to the appropriate directory.
Thanks for everyone's help. As a note, I am really restricted to supporting TexLive versions that ship on stable long-term-support (and supported) distros.... We can argue about whether these distros are too shy about upgrades, but users don't like to hear that their shiny rpm or .deb requires that they also track down large dependencies from external sources not in any repository for their distro.....
