[^crypto-15542.bundle]. You can `git clone crypto-15542.bundle` to check out a working copy.

Running ./src/ossl-config prints a linearized version of the default OpenSSL configuration file to stdout. This should be written to the filename printed by ./src/ossl-files --config.
Running ./src/ossl-files --engines --providers prints a list of all additional files to be copied to the initramfs on stdout, one per line. Note that this currently does not contain potential PKCS#11 modules loaded by PKCS#11 ENGINE or PKCS#11 provider, but for now I'd go with this and only add support for PKCS#11 modules should somebody ask for this later.

The code is tested and works. It still needs to be integrated into dracut, though. At the moment, https://github.com/dracut-ng/dracut-ng/blob/main/modules.d/01fips/module-setup.sh#L67 seems to be the only place where an openssl configuration is copied into the initramfs, and probably needs to be adjusted
