I'm trying to make the switch to netcfg but it fails in mulltiple ways.

1) apparently a warning only when connecting to wlan:
nl80211: 'nl80211' generic netlink not found

The module is indeed not loaded, but not blacklisted either, it simply
isn't there (can't modprobe it manually).

2) Ethernet seems to only work in debug mode:
$ sudo NETCFG_DEBUG="yes" netcfg ethernet-dhcp

                                                                                                                                                       [FAIL] 3) static ethernet doesn't work at all:
$ sudo NETCFG_DEBUG="yes" netcfg ethernet-moheim-static 
DEBUG: Loading profile ethernet-moheim-static
DEBUG: Configuring interface eth0
:: ethernet-moheim-static up                                                                                                                           [BUSY] DEBUG: status reported to profile_up as:

                                                                                                                                                       [FAIL]

Pretty disappointing, considering that rc.conf and a really dumb bash script just works.
The dhcp config is straight from the examples, the static one looks like
this:
CONNECTION='ethernet'
DESCRIPTION='A basic static ethernet connection using iproute'
INTERFACE='eth0'
IP='static'
ADDR='143.205.216.123'
GATEWAY='143.205.216.255'
DNS=('143.205.64.51','143.205.64.52','143.205.176.16','143.205.176.17')

Any ideas what's wrong?
