Undocumented /etc/bash.bashrc
In 4.4: rename (move out of the way) /etc/bash.bashrc to prevent it affecting the lfs user environment. (Note: manual says can restore it after the project.) Ubuntu has an /etc/bash.bashrc, I don’t know which other distros have it or not. The LFS manual just refers to it as “undocumented.” So far I am sensing some…

Excuses, excuses
So in August there was some water intrusion in the basement and I wasn’t able to work on LFS for some weeks / months. Still going to do LFS. I would hate if it took me YEARS however.

Typos
Man, the typos I’m making in these posts… I hope no one is copying exactly what I do without verifying it… Me and Google AI Mode have something in common after all… I’m trying to correct stuff as I see it…

Adding the LFS User
Ch. 4.3 of the manual. Add LFS user and group sudo groupadd lfssudo useradd -s /bin/bash -g lfs -m -k /dev/null lfs This adds user lfs, -m creates a home directory for user lfs-k /dev/null prevents something-s /bin/bash makes bash its default shell.

(Not) updating Ubuntu
“Not all updates can be installed. Run a partial upgrade…” I decide to do nothing. Do I have a development version of Ubuntu? lsb_release -a No. I see Ubuntu 24.04.3 was released on August 7th. Some conversations on the topic: https://askubuntu.com/questions/1443779/why-doesnt-this-software-updater-warning-tell-me-what-is-going-to-be-installed https://askubuntu.com/questions/1554162/ubuntu-24-04-is-asking-for-a-partial-upgrade https://www.reddit.com/r/Ubuntu/comments/1mjhbag/ubuntu_2404_is_offering_a_partial_upgrade/ I also notice that the versions are referred to as “Focal” and…

For Loop from Hell
The next part of LFS Ch. 4.2, creating a limited directory layout. Descent into Hell The manual says: As root, for i in in lib sbin; do ln -sv usr/$i $LFS/$i done Google AI Mode explained that the “usr” in this code is relative to $LFS and therefore will be in $LFS and not in…

Creating limited directory layout
Beginning LFS 4.2. I think this was the first of what was eventually five lines of code (three of which exactly as in the manual) that took two hours with Google AI Mode to establish and then quite a lot of time to carry out. Edit: That’s because it was supposed to be done with…

Finishing up LFS section 3.1
After everything is downloaded, finish section 3.1 by cleaning up the owners of the downloaded files. Check $LFS variable and that it is mounted echo $LFSmount Change all owners to root rather than to who downloaded them (as I understand it): sudo chown root:root $LFS/sources/*
