Ok...I'm getting closer. My testing was as root, so now I'm testing as
mythtv user. My mythtv setup has this as the shutdown script:
sudo sh -c 'echo $time > /proc/acpi/alarm'
However, when I try (logged in as mythtv) to run the above (with a real date
time)I get:
bash: /proc/acpi/alarm: Permission denied
So...I checked my /etc/sudoers and I see these two lines (which should allow
the mythtv user to access acpi/alarm):
Cmnd_Alias MYTHDORA
/usr/share/mythdora/dorabackup,/usr/share/mythdora/mythdorasetup.pl,/sbin/se
rvice,/bin/mount,/bin/chmod,/bin/umount,/sbin/chkconfig,/usr/share/mythdora/
killbackend.sh,/usr/bin/k9copy,/usr/bin/wlassistant,/proc/acpi/alarm
ALL ALL=(ALL) NOPASSWD: MYTHDORA
Why would I still get a password prompt when mythtv user is trying to write
to /proc/acpi/alarm ?
Thanks,
MD
