Default location of TEXMFLOCAL with alternate installation path

[Magnus Ekhall]

Hi Karl,

> 1) Did you rename the install-tl directory manually? Ordinarily it would be named "install-tl-20220608", afaik. Just wanting to be sure we're talking about the same version, since ...

Indeed, I encountered this issue when using an older version but I got the same result with the latest version. That is why the lines does not match. And the install is being made through Chocolatey, but that should not matter much I guess. The patch I wrote is towards the latest revision though.

Now, my perl skills are not something to brag about so I may well be wrong here. But I think that abs_path works with the current filesystem and can indeed return an undefined if you try to get an absolute path to a location that does not exist.

If I print 
$vars{'TEXDIR'}.'/../texmf-local' 
I get: 
c:\users\magnus\texlive-installation/../texmf-local

And that looks fine to me... abs_path() does indeed return an undefined, and according to the manual it sets $! when that happens.

In my case $! Is set to: "No such file or directory"

Where in install-tl is the $vars{'TEXDIR'}.'/../texmf-local' directory created? Could it be that the directory has not been created and thus abs_path fails?
