That is correct. Limit is applied to the socket when it is created
(sk->sk_max_ack_backlog = net->unx.sysctl_max_dgram_qlen;).

I believe using dropin services should work as well as handling this
in linuxrc or ramfs. I was more after an upstream solution then per
user solution but since we are all on the same page regarding the
kernel fix for per socket limit, I guess I need to solve it in my
application. Thanks for the help.
