About texmf-var folder in PREFIX

[angelog0]

I just noticed that under $PREFIX there is that folder:

$ ls -lrt $PREFIX/
[...]
drwx------   3 u0_a241 u0_a241  4096 Jul  8 15:27 texmf-var    ## <== See HERE
drwx------  48 u0_a241 u0_a241  4096 Jul  8 16:41 share
drwx------   2 u0_a241 u0_a241  4096 Jul 10 14:26 tmp
drwx------   3 u0_a241 u0_a241 36864 Jul 10 14:26 bin
drwx------  22 u0_a241 u0_a241 20480 Jul 10 14:26 lib

It contents

It seems created when updating TeX Live with the tlmgr ... --list/self/all

Deleting or renaming it to something else, does not matter: it is recreate the next time.

It does not seem to be necessary to TeX Live to work. On another device, on which I just copied the $PREFIX/share/texlive directory and on which this installation works, I don't have that folder at all because on this 2nd device I don't upgrade TeXLive with tlmgr but just synchronize the folder from 1rst to 2nd device.

On GNU/Linux installation, its content lives in the same texmf-var folder which is under the main TeX Live installation folder (your $PREFIX/share/texlive).

I think the same should happen in Termux... Why NOT?

[Grimler91]

Either there is an additional place where we need to replace SELFAUTOPARENT with TEXMFROOT, or tlmgr upgrades itself and reverses the patch we apply, and then uses the wrong texmf-var when installing/upgrading additional packages.

The former seems more likely.

[Grimler91]

Since all the files are luatex related there is probably a luatex script that needs to be patched

If none has a solution, it does not mean the bug is fixed... Maybe we have to ask upstream..
