See this when installing on Arch Linux

# /root/.TinyTeX/bin/x86_64-linux/tlmgr option sys_bin
Destination for symlinks for binaries (sys_bin): /home/runner/bin

The installation was done with quarto install tool tinytex

This means that when doing tlmgr path add with the monthly bundle version, then /home/runner is created. I don't think that is right.

I am seeing that we do a post install configuration on TinyTeX:
https://github.com/rstudio/tinytex/blob/main/R/install.R#L461-L480

Is this to solve such issues ? Or was it for something else ?

is the fact that tlmgr option sys_bin is set to a value from the GH runner a limitation of our bundles ?

Maybe it is known and already documented but somehow I was suprised.
