Unable to use a freshly-built bundle

[rm-dr]

I'm trying to build a set of texlive bundles using the documented commands:

./driver.sh build-image
./driver.sh update-containers
./driver.sh make-installation bundles/tlextras
./driver.sh install-packages bundles/tlextras
./driver.sh make-zipfile bundles/tlextras
./driver.sh make-itar bundles/tlextras

I'm building against Texlive 2022 (tags/texlive-2022.0 in the git repo)

They all complete successfully, but tectonic refuses to compile latex documents using the bundle. With the V2 interface, the following Texlive.toml works:

[doc]
name = "Test"
bundle = "https://data1.fullyjustified.net/tlextras-2022.0r0.tar"

[[output]]
name = "main"
type = "pdf"

And the one below doesn't, failing with the following error. test/formats.py also fails for the same reason.

[doc]
name = "Test"
bundle = "file:///REDACTED/tectonic-texlive-bundles/state/artifacts/tlextras-2022.0r0/tlextras-2022.0r0.zip"

[[output]]
name = "main"
type = "pdf"

error: latex.ltx:10583: Undefined control sequence
error: halted on potentially-recoverable error as specified

I'm using tectonic 0.14.1. What's going on?

[rm-dr]

Update:

The following lines of latex.ltx in the zip bundle seem to be causing an issue: \ (These are lines 10582-10601, the first line after \ifx triggers the error above)

\ifx \Umathcode\@undefined  \else

\DeclareTextSymbol{\textcentoldstyle}  {TS1}{139}
\fi               % --- END of Unicode engines specials

I removed these lines and built all my documents using the new bundle. Everything worked.\ (Of course, maybe removing those lines broke a feature I've never used.)

diff says that the latex.ltx in the repo and the latex.ltx in the currently active tarball are identical.

---

I forked this repo, reworked the build process, and built a bundle from texlive2023.0r0 without any patches. It worked. Maybe the patches for tl2022 are bad?

[rm-dr]

In my quest to get tectonic working on my documents, I forked and rewrote the bundle-building code in this repo.

It's not done yet, but building and configuring bundles is already much easier than before.\ I also have a working texlive2023.0r0 bundle, which resolves #12.
