Bug 2209220

I found that there was a similar problem in void linux. Someone mentioned that:

I just looked into this a bit more, and apparently SELFAUTOPARENT is just 2 directories up from the location of kpsewhich (or some other executable that serves a similar role, I'm not sure). In a manually installed texlive disribution, this would end up being the texlive root directory. However, void puts kpsewhich in /usr/bin, so SELFAUTOPARENT is would be set to /. But, separately to that, there seems to be bug in ConTeXt's file.collapsepath which causes it to collapse /usr/bin/../.. into ..

It would be helpful to read the following command line show some weird message:
```sh
mtxrun --generate

Good catch. I think this will be resolved in the latest texlive-base update, with the config fixes I now get useful output when I run: mtxrun --script fonts --list --all

FEDORA-2023-38094d905c has been submitted as an update to Fedora 38. https://bodhi.fedoraproject.org/updates/FEDORA-2023-38094d905c

FEDORA-2023-38094d905c has been pushed to the Fedora 38 testing repository.
Soon you'll be able to install the update with the following command:
`sudo dnf upgrade --enablerepo=updates-testing --refresh --advisory=FEDORA-2023-38094d905c`
You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2023-38094d905c

See also https://fedoraproject.org/wiki/QA:Updates_Testing for more information on how to test updates.

After installation of the fix FEDORA-2023-38094d905c, the script mtxrun works. The old luatex ccache should be manually remove by
```sh
$ rm -rf ~/.cache/texlive
```
but in TeX Live 2023, the following command line
```sh
$ mtxrun --script cache --erase
```
do the same thing.

There are some suggestions on improvements for texlive-base:
1. Could you make a soft link from /usr/share/texlive/texmf-dist/web2c/texmfcnf.lua to /etc/texlive/web2c/texmfcnf.lua? All configurations should be placed into the directory of /etc. 
2. Could you adjust the texmfcnf.lua such that there is a user-defined configuration file for ConTeXt engine, e.g. ~/.texmf-config/web2c/texmfcnf.lua? Actually, without this modification, the environment variable OSFONTDIR is necessary for ConTeXt. 
3. Could you adjust the directory structure of /usr/share/texlive according to Linux FHS, e.g. /usr/share/texmf /usr/local/share/texmf, /etc/texmf... In my memory during I used the texlive on gentoo box, they followed the rule of FHS.

FEDORA-2023-38094d905c has been pushed to the Fedora 38 stable repository.
If problem still persists, please make note of it in this bug report.

I will make this change in Fedora Rawhide, it will be picked up in Fedora 39+.

Could you suggest a specific change to texmfcnf.lua that would resolve this for you?

We used to do this, but some things expected to find the standard texlive layout and when they did not find it, they broke in weird ways. I'm reluctant to make this already challenging packageset more complex just to make FHS happy. :)
