So i install this build, no problem here in 1 day.
Upgrade is done via web iface, all services are up and running, plus rtorrent, squid, tor, some rrd scripts too.
Everything look fine, cpu is under 5% with spikes from ntpd every hour.
I cant see any changes, web browsing is good, but was good before -d, i have 8M/1M, and cpu was same before this.
Single thing i see is stable, so anyone can use -d without fear, even for testing.
And no pppd here, nor dhcpd on wan, i have fixed ip .
