* kernfs: reword the description of bind mountXi Ruoyao2022-11-181-2/+2
| | | | | | | | | | | "Duplicated copy" is wrong IMO. If you copy A to B, B won't be changed when you modify A. But if you bind mount A to B, B will reflect any change made to A. Again copy something from mount(2): A bind mount makes a file or a directory subtree visible at another point within the single directory hierarchy.
* kernfs: remove a false noteXi Ruoyao2022-11-181-2/+1
| | | | | | | | | | | | | | | | | | | | | Things are a little tricky: 1. If the host is "modern" (any desktop distro after 2013), the kernel supports devtmpfs and the host udev will do adjustments to the devtmpfs. All instances of devtmpfs shares the same content so we'll see the work of both the kernel and the host udev in chroot. 2. If the host is old but the kernel supports devtmpfs (i. e. the host is not using devtmpfs for its /dev), when we mount devtmpfs on $LFS/dev we'll see the work of the kernel in chroot, but not the work of udev. **Building LFS does not need any work of udev.** 3. If the host is very old and the kernel does not support devtmpfs at all, we can't mount devtmpfs. Mounting a devtmpfs will work for 1 and 2, while bind mounting will work for 1, 2, and 3. So we use bind mounting here. I don't want to squash all these details into the book, so just remove the false statement here.
* chroot: reword how chroot worksXi Ruoyao2022-11-181-3/+4
| | | | | | | | | | | | | | | Technically chroot command "tells" bash nothing. It basically calls chroot("$LFS"), then chdir("/"), then execve(["/usr/bin/env", "-i", ...]). The kernel also does not tell bash something like "hey, the root is now $LFS" but just executes (almost) all system calls from bash as-if $LFS is /. The man page of chroot says: DESCRIPTION Run COMMAND with root directory set to NEWROOT. Just use the same grammar construction here.

* kernfs: "device nodes" are in /dev, not "devices"Xi Ruoyao2022-10-011-1/+1
| | | | You cannot throw a NVIDIA GTX 690 into /dev :).
* kernfs: modernize the explanation for bind mounting /devXi Ruoyao2022-10-011-10/+21
| | | | | | | | | | | | | If you are using a "modern" distro (with devtmpfs and a modern udev implementation), a bind mounting is actually not needed because you can mount devtmpfs anyway. The only reason for bind mounting is to be compatible with old host distros where /dev is a directory containing many static device nodes, or is a tmpfs (not same as devtmpfs) popluated by bootscript or an old udev (modern udev implementations, including eudev and systemd-udev used by LFS, strictly requires a devtmpfs on /dev). So update the explanation to match the status quo.
* kernfs: technically, they are not needed for chrootXi Ruoyao2022-10-012-3/+3
| | | | | | | | | | | | | Chroot command itself does not require kernel VFS mounted. You can mount /proc, /sys, and /run after entering chroot with "mount -v -t proc proc /proc" etc. For /dev, if the host kernel supports devtmpfs, you can also mount /dev in chroot with "mount -v -t devtmpfs devtmpfs /dev". Even if the host does not support devtmpfs, it's still possible to mount /proc in chroot, then use "mount --bind /proc/1/dev /dev". It's just LFS editors decide to mount them before chroot. So reword some untrue assertions.

* Made grammatical corrections and stylistic changes to chapter 7.3.David Bryant2022-09-301-15/+17

* Adjust instructions for /dev/shm when creating virtual filesystems.Bruce Dubbs2022-09-202-1/+9
| | | | | | | | | | Some host create /dev/shm as a tmpfs. Some have is as a symlink to a location in another directory. This change handles both cases. The change to the sysV bootscripts now creates /dev/shm as a separate tmpfs from /run. This makes LFS sysV and systemd versions treat /dev/shm the same.
* cleanup: rephrase description for .la removalXi Ruoyao2022-09-191-4/+4
| | | | | | Don't emphasis "static library" at all, to prevent anyone from thinking "I need to use static libraries so I'll keep these .la files". And warn that .la files are known to break BLFS packages.

| | | | | | | | | | | | | | | | | | | | It works out of box with glibc-2.35. I think this issue is already fixed at glibc side, by the commit: commit 0b5ca7c3e551e5502f3be3b06453324fe8604e82 Author: Paul Eggert <eggert@cs.ucla.edu> Date: Tue Sep 21 07:47:45 2021 -0700 regex: copy back from Gnulib Copy regex-related files back from Gnulib, to fix a problem with static checking of regex calls noted by Martin Sebor. This merges the following changes: * New macro __attribute_nonnull__ in misc/sys/cdefs.h, for use later when copying other files back from Gnulib. ... ... (unrelated things trimmed)
* revise the note about "already created" directoriesXi Ruoyao2022-05-301-4/+4
| | | | | | | | | | Q: Why not just move the note after the creation of root-level directories? A: Root-level directories may be already created as well: if a root-level directory is a mount point it should have been created in section "Mounting the New Partition".

* kernfs: "Udev" -> "the kernel and Udev"Xi Ruoyao2022-03-081-1/+2
| | | | | devtmpfs already contains many device nodes created by the kernel once it's mounted, and Udev creates or renames nodes based on kernel work.
* kernfs: remove static node creation, and update the textXi Ruoyao2022-03-081-32/+13
| | | | | | | | | | | | | | | | | | This is to match the "new" way of device handling with devtmpfs (already widely used in recent ten years). In a normal booting process, the kernel mounts devtmpfs at very early stage. So the static nodes won't be used at all. The only situation where the kernel can't mount devtmpfs is "/dev is missing", but it means those two static nodes can't exist anyway, and a normal LFS system (without initramfs) won't boot in such a bad situation. Removing static /dev/console and /dev/null may cause trouble for those people or scripts chroot into LFS tree without mounting devtmpfs. But entering a chroot with only console and null in /dev is already problematic. For a reference, If a systemd service is started with PrivateDevices=true, systemd will create 18 nodes and symlinks to form a "minimal" /dev.
* fix GCC PR100017 and enable libstdc++ for pass 2Xi Ruoyao2022-02-272-121/+0
| | | | | | | | | This is the issue preventing us from cross-compiling libstdc++ in Chapter 6. By fixing this issue we can remove a seperate pass 2 for libstdc++ and simplify the instruction. The upstream fix will be released in 11.3 and 12.0, so we can remove the first sed upgrading gcc next time.

* remove "+h" in bash commands in chroot (#4998)Xi Ruoyao2022-02-052-13/+3
| | | | | | | | | | | | | | | In the new cross-compilation approach, the $PATH in chroot does not contain '/tools/bin'. So "+h" is useless in chroot as the newly installed tools always replace the temporary counterpart at the same location. "+h" in chapter4/settingenviron.xml is kept deliberately. Currently $LFS/tools/bin only contains programs prefixed with "x86_64-lfs-linux-gnu-", and it's highly unlikely that any distro will ever ship a program named with such prefix. So it may seems that we can remove this "+h" as well. However, the situation may change in future and we can take this oppertunity to teach the advantage and disvantage of bash hash feature.
