the recordings are created without group write

I need to chmod g+w <br>

<p>That assures new files are members of the same group as
the directory, which they are (mythtv). That does NOT
give group write permission to the file so I still have
to chmod it (g+w) before I can write to it. Another
thing I just tried was</p>
<p>setfacl -dm group:mythtv:rwx
<storageGroupDirectory></p>
<p>but even that didn't work. It's as if mythbackend is
specifically setting the mode. I've worked around it
with a cron job that runs every night as root just
before my "fix decoder errors" to chmod g+w on all files
in the recordings directories, but that seems like such
a hack and new files aren't "fixed" until the next cron
job runs. I've spent WAY too much time on this. On to
other things...<br>

<div>Are you using systemd to manage the mythbackend process?
If so take a look at:</div>

<p>Yea, thanks for posting that but already been there. Verified
with systemd-analyze dump that new umask is set, tried systemctl
daemon-reload and restarted mythbackend, no change. Thanks again,</p>
