[OS X TeX] /usr/local/texlive/texmf-local/ls-R: Permission denied; MacTeX 2017/High Sierra

[Rowland McDonnell]

Hello,

I've just installed MacTeX 2017 on macOS High Sierra v10.13.1

I want to add system-wide local additions, so I copied my usual 
system-wide additions to:

/usr/local/texlive/texmf-local

as I've done previously.

I followed the instructions here:

http://tug.org/fonts/fontinstall.html

to set up my additional fonts for the new installation.  All 
files are in appropriate places, so I ran the following Terminal commands:

sudo -H mktexlsr
sudo -H updmap-sys --force --enable Map=local_extras.map
sudo -H mktexlsr

Everything seemed in order, so I tried LaTeXing a simple test 
document to verify that my locally-added package and fonts were 
available (one of which is Monotype Joanna):

\documentclass{article}
\usepackage{joanna}% load Monotype Joanna and other fonts to match
\begin{document}
Hello world.
\end{document}

This didn't work as expected - the locally-added ls-R file was unreadable:

/usr/local/texlive/texmf-local/ls-r: Permission denied
/usr/local/texlive/texmf-local/ls-R: Permission denied

! LaTeX Error: File `joanna.sty' not found.

I checked permissions etc on the file in question using ls -la:

-rw----r--   1 root     admin  38783 23 Nov 16:12 ls-R

Finder.app tells me that permissions on that file are:

system: Read & Write
everyone: Read only

I couldn't open the file in TextEdit. The Finder said:

The document “ls-R” could not be opened. You don’t have permission.

Just to check I wasn't missing anything obvious, I tried;

kpsewhich --var-value TEXMFLOCAL

which gave an output of:

/usr/local/texlive/texmf-local/ls-r: Permission denied
/usr/local/texlive/texmf-local/ls-R: Permission denied
/usr/local/texlive/texmf-local

I made a copy of the troublesome ls-R file using the Finder's 
File->Duplicate command and I could open that (filename: ls-R 
copy) without trouble in Textedit.app.  It's got the expected contents.

I then moved the ls-R file created by sudo -H mktexlsr and 
renamed ls-R copy to ls-R using the Finder.

My test document then LaTeXed exactly as expected.

I don't understand this problem since the mktexlsr created ls-R 
seems to have appropriate permissions as far as I understand it, 
but obviously the machinery thinks otherwise.

This looks like a problem which needs investigating - or have I 
done something wrong?

I'd appreciate any comments.

Cheers,
Rowland.
