nm cannot correctly set interface as unmanaged

[Simone <iceee2k3 gmail com>]

Hi,

 since I fresh-installed ubuntu 10.04 with the new network-manager(NM)[1] I'm no
longer able to manually setup my network editing "/etc/network/interfaces".

I have two interfaces manually configured[2]:
- eth0, manually configured to use dhcp, is correctly set UNMANAGED by NM.
- eth1, manually configured to use a static ip address, is NOT set
  *unmanaged* by NM, that starts a dhclient on it.

The only workaround I found to set "eth0" and "eth1" UNMANAGED in NM is to set
"NetworkingEnabled=false" in "/var/lib/NetworkManager/NetworkManager.state"[4].

I also tried to configure[3] "eth0" and "eth1" to use dhcp. The result is that
NM works as expected, setting the two interfaces UNMANAGED.

Could this strange behavior be a bug?


Thank you in advance!,
  Simone
