Hey Alan!

 AI> I just booted my first lfs build yesterday. Linux 6.1.2, 
 AI> bash 5.2.15 and a recent version of vim.

I just booted kv-6.1.2 early yesterday morning;
 > :r !cat /proc/version | sed 's/^/ > /'
 > Linux version 6.1.2 (root@motorshed) (gcc (GCC) 12.2.0, GNU ld (GNU Binutils) 2.39) #1 SMP PREEMPT_DYNAMIC Sun Jan  1 05:22:50 UTC 2023

 AI> What a beautiful thing.. :)

Agreed.  As far as I am concerned it is the absolute best thing that happened to any computer.

 AI> I just need to add a *.eth0 to setup the network (I think).

Yes.  On the three lfs systems here, there are two - eth0 and eth1.  One is for static IPs on cable, the other for my wired private network.  Also wireless hostapd but those are customized setups with their very own extra-special rc scripts.  If you want to have a looksee at any of the /etc/sysconfig/ifconfig.eth? don't hesitate to ask and I can netmail then to you.  However I think they are pretty straqight forward once you see them in action.

 AI> but it uses static IPs and mine is dynamic, my slackware setup 
 AI> gets the IP with dhcpcd

Right.  See https://www.linuxfromscratch.org/blfs/view/svn/basicnet/dhcpcd.html for all the gory details.  It isn't installed by LFS so you'll need to add it following the BLFS instructions.  Same with wpa_supplicant for automagic wireless configurations for client systems.

 AI> I wonder if I need to install and setup dhcpcd

Yes you do.  I think https://www.linuxfromscratch.org/blfs/view/svn/basicnet/dhcpcd.html is the answer to all your questions but if not I believe I have some insight that will take it over the top.

WARNING:  LFS is extremely addictive.

Life is good,
Maurice
