[mythtv-users] Why does /dev/dvb reset permisions on boot?
Hi folks, Probably an obvious question (bit of Linux newbie here I'm afraid) but why would the permissions on my dvb devices reset to allow just root access each time I reboot? Myth can't access them as the 'mythtv' user doesn't have write permission but I change this using chmod... it just can't retain the change...

if you are using a actual distribution, you may not have a static dev directory, this directory is created every time on boot via udev. you have to look at /etc/udev/permison.rules or so... - Original Message - From: ffrr [EMAIL PROTECTED] To: Discussion about mythtv mythtv-users@mythtv.org Sent: Tuesday, December 06, 2005 9:59 AM Subject: Re: [mythtv-users] Why does /dev/dvb reset permisions on boot?

Myth can't access them as the 'mythtv' user doesn't have write permission but I change this using chmod... it just can't retain the change... udev issue - the cleanest solution is to write your own rules for DVB (and other) devices - the following page is a great introduction to udev and should get you sorted: http://www.reactivated.net/udevrules.php Essentially, create the rule for the DVB devices by coping the content of the existing udev rules file (which could get overwritten if udev is updated) and create a new rule file (with a filename that is alphanumerically less than the name of the main rules file) with the amended owner/group/permissions. These settings will then be applied everytime the machine starts. I created various groups (e.g. audio/video/lirc) when configuring my various udev devices and then add users to these groups when they require access.
