Hello Org!
I attached a patch that is required to get ox-odt to work on
guix/nix/other distributions where package files are placed in a
read-only directory. After the file styles.xml is copied to /tmp, now
we set read-write permissions to it before trying to write it. Before
this patch, we got the error:
'OpenDocument export failed: Buffer is read-only: #<killed buffer>'.
It's my first patch and is just 1 line long, so following instructions
on https://orgmode.org/worg/org-contribute.html#commit-messages I added
the TINYCHANGE cookie. Tests (make test) are passing.
Thanks!
Nicolò

Subject: [PATCH] ox-odt.el: (org-odt-template): Get write permissions on
styles.xml
To: emacs-orgmode@gnu.org
(org-odt-template): The file `styles.xml' might be copied from a
location where it is read-only. Since we need to modify it (and its
copied under /tmp, so we can modify it), we need to ensure we have
write persmissions on it. Set mode to 600.
This is especially needed for projects like guix, where all system
files are stored in a read-only location.
