[XeTeX] How to manually create the xelatex.fmt?

[Chris Travers]

The general point is that where one is doing server-side document
generation, there are sufficient reasons *not* to use external binary
blobs with it's own package manager that doesn't talk to or integrate
with anything else, which has a short support cycle, and which is
statically linked to all its dependencies.

Use of distro packages may not be perfect, but the only two options
are that or compiling from source, realistically.

Best Wishes,
