Description Peter Humphrey 2008-06-25 12:02:34 UTC
There seems to be no way to prevent the minimal installation CD from spawning dhcpcd and netplugd. (Version 2007.0 pretended to obey "nodhcp" but the console log still showed dhcp as timing out.)
Things get a bit confused on this box which has 3 NICs of two types, which come up in unpredictable order, and dhcp competing with net-setup to assign the right IP address to the right NIC. Maybe dhcp isn't really a problem, but it doesn't help with understanding what's going on.

Reproducible: Always

Can you verify this with the final 2008.0 media?
Comment 2 Peter Humphrey 2008-07-15 08:11:34 UTC
Yes, on amd64 (it looks as though I forgot to set the hardware flag properly on my first report - sorry). This morning I booted the minimal (final) 2008.0 CD and chose gentoo-nofb, adding "docache vga=0x317 nodhcp" to the existing kernel parameters. The console messages included "* Network device eth0 detected, DHCP broadcasting for IP ...", and the syslog output on ALT-F12 had an endless sequence of timeout and retry messages. Netplugd was also running.

I tried it on another box and got the same result. This also was a 64-bit machine. I could try it on an i686 box if you like, but I go away on holiday in a few days and it may not get done before then.

The "nodhcp" kernel command is honoured ok on my i686 firewall box. Netplugd is still run, however, one instance for each NIC. Should that also be inhibited by "nodhcp"? It doesn't cause me any problems, but it seems not to be needed if I'm going to run net-setup.

... perhaps I should open another report for amd64. X86 does seem ok here, as I said.

The 2008.0 release was done a long time ago.
