As an example, I set
$XDG_CACHE_HOME rwc
$XDG_CONFIG_HOME rwc
$XDG_DATA_HOME rwc
in /etx/firefox/unveil.main and started ktrace firefox.
Here is a snipet from the kdump:

I have no idea why it reports ENOENT/EACCESS.
I have move unveil.main away temporarily and started firefox
- no error messages, apparently it saved the info of firefox
being the default browser (which is what has benn popping up
on every start, but never remembered, presumably because of
these failed writes), and then moved unveil.main back,
and removed the three lines above. There are no such
messages since then.
