hi,
I need to durably change the permissions on /dev/rtc0 so that another user can write to it. Thus, I wrote a udev rule, ran "udevadm trigger" and rebooted. It did not work.
my custom udev file has one line, as follows:
Code:
ACTION=="ADD", ATTR{DEVNAME}=="/dev/rtc0", GROUP="mythtv", MODE="0666"
I saved it as /etc/udev/rules.d/40-rtc-permissions.rules
udevadm info returned the following name for my device:
Code:
/devices/pnp0/00:02/rtc/rtc
When I run
Code:
udevadm test /devices/pnp0/00:02/rtc/rtc
, I get a list of the rules being read, with my rule second on the list (that's good, right?), but then this:
Quote:
Invalid inotify descriptor.
DEVPATH=/devices/pnp0/00:02/rtc/rtc0
DEVNAME=/dev/rtc0
MAJOR=249
MINOR=0
ACTION=add
SUBSYSTEM=rtc
DEVLINKS=/dev/rtc
USEC_INITIALIZED=1681953

and the permissions still are incorrect. What am I doing wrong?
