Not necessarily true. Axel and I added FireWire support to the ATrpms Myth
builds a while ago.

This is correct though.

ATrpms has also packaged up all the requisite FireWire bits, including
libavc1394, libraw1394 and libiec61883, so there's nothing that needs
compiling if using ATrpms.

There was a change in the libiec61883 code that prompted the necessity of a
patch to Myth for FireWire support to work correctly. Its already included in
the ATrpms builds.

You're going about this incorrectly. Everything works perfectly on my box
without a thing in rc.local. For the device node, this...
mknod /etc/udev/devices/raw1394 c 171 0
...will take care of recreating the device node on restarts.
To get the right modules loaded, I just have only these two lines in
modprobe.conf:
alias ieee1394-controller ohci1394
install ohci1394 /sbin/modprobe raw1394; /sbin/modprobe --ignore-install
ohci1394
And that's it.

Its not.

See above. :-)
