Similar to Thunderbolt, supporting FireWire is dangerous as it allows
Direct Memory Attacks, which are known to be actively used by more
sophisticated attackers (https://wikileaks[.]org/spyfiles/files/0/293_GAMMA-201110-FinFireWire.pdf).
Since network hardware using FireWire is diminishing, and there is no
other legitimate reason to use FireWire on an IPFire machine, dropping
support for it looks reasonable to me.

Good morning Peter,
since firewire hardware is basically non-existant for many many years I
do not think that this patch drastically improved the security of the
system.
If an attacker has physical access to the system, other attacks are
possible, too, and firewire is not a necessity.
However, there is no reason left to actually compile this. It wastes
more build power than it is useful.
So I can ack this:
Acked-by: Michael Tremer <michael.tremer(a)ipfire.org>
I suppose that again you didn't build this because there are no roofile
changes?!
Best,
-Michael
