So should it point to lirc0 (inode) or lircd (link to
/var/run/lirc/lircd) or directly to /var/run/lirc/lircd?

If I stop lircd with $sudo /etc/init.d/lirc stop and then remove
lirc_zilog with $sudo modprobe -r lirc_zilog and then load lirc_zilog
with $sudo modprobe lirc_zilog, then two instances of lircd start as
soon as I load lirc_zilog:
/usr/sbin/lircd --output=/var/run/lirc/lircd1 --device=/dev/lircd
--connect=localhost 8765 --pidfile=/var/run/lirc/lircd1.pid
/usr/sbin/lircd --output=/var/run/lirc/lircd --driver=dsp
In other words, it doesn't seem necessary to issue /etc/init.d/lirc
start for lircd to start up (or should I issue that anyway?).
$sudo irsend LIST "" "" still returns nothing while $sudo irsend
SEND_ONCE blaster select returns
irsend: command failed: SEND_ONCE blaster select
irsend: hardware does not support sending
(this seems odd to me, because LIST seems to indicate there is no
device, while irsend seems to indicate there is a device, it just
doesn't support sending).
Is it correct for /dev/lircd to be a symlink to /var/run/lirc/lircd? Or
should this be an inode? Also, is that driver line correct, or should it
point to the HD-PVR driver at /lib/firmware?
Also, while the STBs (and thus the commands lirc transmits) would vary,
wouldn't the config files for all HD-PVRs running on Ubuntu 10.04 be
identical, except for where they issue commands to the STB? In other
words, couldn't I simply copy anyone else's /etc/lirc/lircd.conf and
/etc/lirc/hardware.conf and then just modify the transmit commands to
match my STB? I'm sure others, less mentally challenged than I, have
managed to get this working (I know: I'm being lazy...).
