Managing a complete linux system from scratch can be quite the challenge. Thankfully the FLS and BLFS project exist to give a tremendous hand to the people brave enough to use a LFS system daily.

This directory, located at /lfs contains information about my personal linux system, config files, tips and tricks to make my life easier. To install the config files, I just have to run make install.

This document contains the following sections:

• overview of the system
• users
• package management: how I handle packages
• network
• config files: a list of useful config files

This system was first built the 31/08/2024, with Linux-6.10.5 following LFS 12.2. The installed firmware is tag 20241017.

Note the following directories:

• /sources: important source files such as the linux kernel are kept here, accessible by any user
• /lfs: system documentation
• /boot: linux boot, containing the kernel bzImage and the config file used to build the latest kernel.
• /boot/efi: mount point of the efi partition
• /lib/firmware: firmware programs

The system has 3 users:

• root: privileged user
• santo: regular user in the wheel group
• lanto: unprivileged user without access to sudo

A list of installed packages is located in /lfs/installed.lfs. I am working on a package manager, mapkg, for the most important packages that I want to upgrade when a new version comes out.

The firmware needs rtw88/ for wifi support, which are build inside the kernel. Support for compressed firmware is also enabled but vould be removed. To list all PCI devices and the kernel module they use, run lspci -k

To connect to the internet, the device must be up first. Use "ifup " for wifi, or "ip link set up" and then "dhcpcd" to get an ip address for ethernet. List the network devices with "ip link show".

Public key certificates are stored in "/etc/pki/tls/certs/ca-bundle.crt" and are updated via "make-ca".

• ~/.gitconfig
• /etc/gitconfig

• /etc/sysconfig/wpa_supplicant-wlo1.conf

• /etc/sysconfig/ifconfig.eno1
• /etc/hosts
• /etc/resolv.conf

• /etc/profile

• /etc/sysconfig/mouse

List all the devices and the kernel module associated with them:

lspci -k

Very usefult to understand what a working system is using. If a defice is not showing up, It might be because a kernel module is not loaded. Check dmesg for errors.
