[lfs-support] LFS Version 8.3 released, livecd, PXE

Post by Jean-Marc Pigeon
Hello,
Many thanks to the team for 8.3 Release 'Well done".
Just to let know to the list, I have a 8.3 liveCD and PXE build
using the LFS book and available at URL
https://osukiss.safe.ca//downloads.php
Packaging used is RPM and yum.
My main purpose is to have HOSTs (LFS-8.3) and containers
(Centos, LFS, etc..) and replace openVZ productions system.
(Openvz is a very, very good project but, sadly,fading away :-{ )
Livecd was build (today and from scratch) within an 8.3 container
within a ZFS file system and a 8.3 HOST (production system)
Hoping this liveCD can be of some use for people interested by LFS.
LiveCD is booting under legacy mode (not EFI) on various system
(Dual processor server).

This is a very cool idea, but it does not work for me. It gets to ntpd
and hangs. There is something about a download and waiting 10 minutes.

Is this a systemd based system? If so, can you build a minimal System V
system?

A lot of the packages I see (e.g. crond, atd, dovecot, etc) are not
needed if the iso is to be used as a rescue system. About the only
things I would want are ssh, wget, and a text browser like links.
It would also be better to have a dhcpcd available, but not started
automatically at boot.

Perhaps there should be a few command line utilities also like pciutils,
usbutils, net-tools, gdisk, parted, etc.

- it is systemV
- NTPD is trying to load the the file "leap-seconds.list", my guess is
your DHCP serveur is not providing default route or DNS.
- pciutil, gdisk, wget, sshd are included in liveCD,
"linksi" applcation is available (via yum)
net-tools is not (yet?) available, but inetutils is within
livecd.
usbutils not available, but will be included in liveCD.

Thanks Bruce, I liked you comment.
Matter of fact LiveCD was designed as a demo+install tool
(demo: do we have a minimal workable LFS system set of commands,
install: do we have tools to quickly install/duplicated on system
disk).

But for Rescue process, components as atd, dovecot, ntpd are indeed huge
overkill.
Give me few days to build and validate a "LFS rescue liveCD".

Suggestion from Bruce, have been implemented.

I generated an ISO, which should be usefull in
case you need to fix your LFS.
yum and rpm is included within the ISO, such,
if a tools is missing, you can download it easy
enough. (size is 334 Mbytes)
URL:
https://okrepo.safe.ca/osukiss/8.3/isos/LFS-8.3-rescue-x86_64.iso

Hoping that help LFS users.

I would like to learn how to build a LiveCD. I tried with squashfs
myself but I could never get it running. Could you elaborate please? Or
point to some nice instructions?

Tschau...Thomas

The best I can do is to provide you with an extract of the
Makefile sequence. That will give you "my" way to do it.
Caution: ISO building is relatively easy because I am
using YUM and RPM (yum install packages_list)
Hoping you can use it as frame example for your ISO.

Much better. I was able to boot this on my laptop. It takes about 30
seconds to copy and set things up. The iso size, only 334 MiB, is nice.

There are still a few issues:

1. The 'which' command is not present. The workaround is to use 'type -p'

2. lspci is not present.

3. I'd like a way to set a default for language during the boot sequence
and possibly a font. I like to use terminus fonts, specifically in my
case ter-128n. http://terminus-font.sourceforge.net/

4. It does not recognize either my wired or wireless card. The output
of 'ls /sys/class/net' is only 'lo'. The wireless issue is probably
because firmware (iwlwifi-7260-17.ucode) is not available. However, I
do not think that you should need to install firmware on the iso.

$ lspci|grep -i net
01:00.0 Network controller: Intel Corporation Wireless 7260 (rev 73)
07:00.0 Ethernet controller: Qualcomm Atheros AR8161 Gigabit Ethernet
(rev 10)

My kernel config for the wired connection is:

CONFIG_NET_VENDOR_ATHEROS=y
CONFIG_ATL2=m
CONFIG_ATL1=m
CONFIG_ATL1E=m
CONFIG_ATL1C=m
CONFIG_ALX=m

The ALX module is loaded in my case.

$ lsmod|grep alx
alx 40960 0
mdio 16384 1 alx

I will try this on a more generic system tomorrow at school.

Great work so far.

picutils will be part of next rescue-iso (my mistake)
'which' will be included too.

Included kernel is configured with the exact same config
as yours.....but.. CONFIG_ALX is NOT set!...
(see file /boot/config-4.18.1-0.10.29.ok_8.3 once
you have the iso booted).
This is mot likely the problem, as eudev is not able to discover
WIFI card and populate /sys/class/net

Let me generate a new rescue ISO including your findings.
(Many thanks).

What I should get is:

$ ls /sys/class/net
eth0 lo wlan0

Setting CONFIG_ALX should do it for the eth0 connection. The firmware
is needed for wlan0, but I'm OK without it.

New Rescue ISO:
https://okrepo.safe.ca/osukiss/8.3/isos/LFS-8.3-0.10-39-rescue-x86_64.iso

This include terminus-font and /etc/sysconfig/console is
preset to FONT=ter-128n.
(nice font, I was not aware about terminus-font, thank
for the hint).

alx module part of kernel.

kernel-firmware-20180807 is available via 'yum'. Provided
you have eth0 up and running (dhcp-client) with a default route
and /etc/resolv.conf contents set via your dhcp server config.

Keep me posted.
