记录一些在安装 LFS 时踩的一些坑和其他值得一提的事情。
|

|
||

|
||
|
||
## LFS
|
||
|
||
以下内容按照对应章节划分：
|
||
|
||
- [2.4. Creating a New Partition](https://www.linuxfromscratch.org/lfs/view/stable/chapter02/creatingpartition.html)
|
||
|
||
虽然此处列举了很多分区，例如 `/opt`，`/usr/sources` 等，但我并不喜欢，也并不觉得有必要将根目录分得如此细碎。对于 UEFI 引导的系统来说（btw 我不认为 BIOS 引导和 UEFI 引导的配置难度之间的差距有很多观点说得那样巨大）除去可选的 Swap 分区外通常 `/`，`/boot`，`/boot/efi`，`/home` 几个分区就足够了。
|
||
|
||
- [2.6. Setting the $LFS Variable and the Umask](https://www.linuxfromscratch.org/lfs/view/stable/chapter02/aboutlfs.html)
|
||
|
||
`$LFS` 变量很重要！建议写到 Host 的 `/root/.bash_profile` 或 `/etc/profile.d/...` 或类似作用的配置文件里防止忘记设置。
|
||
|
||
- [2.7. Mounting the New Partition](https://www.linuxfromscratch.org/lfs/view/stable/chapter02/mounting.html)
|
||
|
||
可以用一个小脚本挂载分区，推荐使用文件系统 UUID 而非诸如 `/dev/sdc1` 这样的绝对路径：
|
||
|
||
```bash
|
||
#!/bin/bash
|
||
|
||
[ -z "$LFS" ] && exit 1
|
||
|
||
set -euo pipefail
|
||
|
||
# 替换为实际的 UUID
|
||
UUID_EFI="{ESP_UUID}"
|
||
UUID_BOOT="{BOOT_UUID}"
|
||
UUID_LFS="{ROOT_UUID}"
|
||
UUID_HOME="{HOME_UUID}"
|
||
|
||
ensure_device() {
|
||
local uuid="$1"
|
||
local path="/dev/disk/by-uuid/$uuid"
|
||
if [ ! -e "$path" ]; then
|
||
echo "Device with UUID $uuid not found at $path" >&2
|
||
exit 1
|
||
fi
|
||
echo "$path"
|
||
}
|
||
|
||
mkdir_p() {
|
||
local d="$1"
|
||
if [ ! -d "$d" ]; then
|
||
mkdir -p "$d"
|
||
fi
|
||
}
|
||
|
||
mkdir_p "$LFS"
|
||
|
||
DEV_LFS="$(ensure_device "$UUID_LFS")"
|
||
DEV_BOOT="$(ensure_device "$UUID_BOOT")"
|
||
DEV_EFI="$(ensure_device "$UUID_EFI")"
|
||
DEV_HOME="$(ensure_device "$UUID_HOME")"
|
||
|
||
mount "$DEV_LFS" "$LFS"
|
||
|
||
mkdir_p "$LFS/boot"
|
||
mount "$DEV_BOOT" "$LFS/boot"
|
||
|
||
mkdir_p "$LFS/boot/efi"
|
||
mount "$DEV_EFI" "$LFS/boot/efi"
|
||
|
||
mkdir_p "$LFS/home"
|
||
mount "$DEV_HOME" "$LFS/home"
|
||
```
|
||
|
||
- [3. Packages and Patches](https://www.linuxfromscratch.org/lfs/view/stable/chapter03/chapter03.html)
|
||
|
||
强烈建议通过镜像站下载打包好的所有源代码和 patch，否则某些源服务器的下载速度即便在非受限的网络环境也很感人。
|
||
|
||
- [4.5. About SBUs](https://www.linuxfromscratch.org/lfs/view/stable/chapter04/aboutsbus.html)
|
||
|
||
SBU 只提供大概的预期耗时范围，误差是很大的，尤其对于 BLFS 书中的一些编译时间很长的包（如 Qt，Firefox）来说。
|
||
|
||
- [5. Compiling a Cross-Toolchain](https://www.linuxfromscratch.org/lfs/view/stable/chapter05/chapter05.html)
|
||
|
||
从这一章开始将会手动编译大量的包，其中有不少操作是重复的，例如 `tar -xf`，`cd`，`rm -rf` 等，为此可以写一个小脚本节省时间：
|
||
|
||
```bash
|
||
#!/bin/bash
|
||
|
||
set -euo pipefail
|
||
|
||
[ -z "${1:-}" ] && {
|
||
echo "Usage: $0 <tarball>"
|
||
exit 1
|
||
}
|
||
|
||
tarball=$(realpath "$1")
|
||
|
||
dir=$(tar -tf "$tarball" | sed -e 's/^\.\///' | cut -d/ -f1 | sort -u)
|
||
|
||
if [ "$(echo "$dir" | wc -l)" -ne 1 ]; then
|
||
echo "Error: Tarball must contain a single top-level directory."
|
||
exit 1
|
||
fi
|
||
|
||
cleanup() {
|
||
echo "Cleaning up..."
|
||
cd ..
|
||
if [[ -z "$dir" || "$dir" == "/" || "$dir" == "." ]]; then
|
||
echo "Error: Unsafe directory for cleanup: $dir"
|
||
exit 1
|
||
fi
|
||
rm -rf "$dir"
|
||
}
|
||
|
||
trap cleanup EXIT INT TERM
|
||
tar -xvf "$tarball"
|
||
|
||
if [ ! -d "$dir" ]; then
|
||
echo "Error: Failed to extract directory: $dir"
|
||
exit 1
|
||
fi
|
||
|
||
cd "$dir"
|
||
|
||
echo "Spawning shell. Type 'exit' to finish and cleanup."
|
||
|
||
bash
|
||
```
|
||
|
||
它的作用是解压一个只含有一个顶层目录的 tarball，cd 进入解压后得到的目录，生成一个 shell，并在这个 shell 退出时清理先前解压得到的文件。
|
||
|
||
另外还有对于在 LFS 与 BLFS 中编译包的一些通用建议：
|
||
|
||
1. 通常来说，应该（或者说请务必）在编译和安装一个包后完全删除它的目录，仅有少数例外：
|
||
|
||
- linux（保留构建树可以缩短重新构建耗时，或至少保留 config 便于复原配置）
|
||
- blfs-bootscripts（在 BLFS 中）
|
||
|
||
注意一些需要多次编译的包，例如 gcc，也应该在每次编译与安装后完全删除目录。
|
||
|
||
2. 通常来说，建议将所有相关的 tarball 和 patch 下载在同一个目录中，并且将 tarball 也解压在这个目录中。如果目录层级与该默认情况不一致的话必须修改 LFS 书中提供的命令中对应的相对路径。
|
||
|
||
3. 如果和我一样使用 UEFI 引导，那么大概率将会在 [8.64. GRUB-2.12](https://www.linuxfromscratch.org/lfs/view/stable/chapter08/grub.html) 第一次接触 BLFS。和 LFS 不同，BLFS 中大多数包都是可选的，一个包可能会依赖其他包，这些依赖分为三个层级：
|
||
|
||
- Required
|
||
- Recommended
|
||
- Optional
|
||
|
||
其中 `Required` 是必要的依赖；`Recommended` 通常建议当成 `Required` 看待，除非明确知道对应包的用途和不安装它的影响；`Optional` 酌情安装，很多时候是文档相关的依赖。
|
||
|
||
更多关于安装 UEFI 版 GRUB 的话题将会在之后的章节中讨论。
|
||
|
||
4. 如果想要的包在 LFS 和 BLFS 包中都没有，例如 fish、libglvnd、flatpak 等，不妨先检查 [GLFS](https://www.linuxfromscratch.org/glfs/) 和 [SLFS](https://www.linuxfromscratch.org/slfs/) 或同系列的其他书中是否有涉及，如果有的话将节约很多学习和试错成本。
|
||
|
||
- [7.4. Entering the Chroot Environment](https://www.linuxfromscratch.org/lfs/view/stable/chapter07/chroot.html)
|
||
|
||
对于 chroot 也可以使用一个小脚本显著地改善体验：
|
||
|
||
```bash
|
||
#!/bin/bash
|
||
|
||
[ -z "$LFS" ] && exit 1
|
||
|
||
# mount virtual file systems
|
||
|
||
mkdir -pv $LFS/{dev,proc,sys,run}
|
||
|
||
mount -v --bind /dev $LFS/dev
|
||
|
||
mount -vt devpts devpts -o gid=5,mode=0620 $LFS/dev/pts
|
||
mount -vt proc proc $LFS/proc
|
||
mount -vt sysfs sysfs $LFS/sys
|
||
mount -vt tmpfs tmpfs $LFS/run
|
||
|
||
if [ -h $LFS/dev/shm ]; then
|
||
install -v -d -m 1777 $LFS$(realpath /dev/shm)
|
||
else
|
||
mount -vt tmpfs -o nosuid,nodev tmpfs $LFS/dev/shm
|
||
fi
|
||
|
||
# cleanup (defer)
|
||
|
||
cleanup() {
|
||
echo "Cleaning up..."
|
||
mountpoint -q $LFS/dev/shm && umount $LFS/dev/shm
|
||
umount $LFS/dev/pts
|
||
umount $LFS/{sys,proc,run,dev}
|
||
}
|
||
trap cleanup EXIT INT TERM
|
||
|
||
# chroot
|
||
|
||
chroot "$LFS" /usr/bin/env -i \
|
||
HOME=/root \
|
||
TERM="$TERM" \
|
||
PS1='(lfs chroot) \u:\w\$ ' \
|
||
PATH=/usr/local/bin:/usr/bin:/usr/sbin \
|
||
MAKEFLAGS="-j$(nproc)" \
|
||
TESTSUITEFLAGS="-j$(nproc)" \
|
||
/bin/bash --login
|
||
```
|
||
|
||
它的作用是自动挂载一系列虚拟文件系统，同时在退出 chroot 时自动清理。
|
||
|
||
> [!IMPORTANT]
|
||

|
||
> 此处并不建议使用 `arch-install-scripts` 提供的 `arch-chroot` 偷懒，除非明确知道自己在做什么。
|
||
|
||
- [8.64. GRUB-2.12](https://www.linuxfromscratch.org/lfs/view/stable/chapter08/grub.html)
|
||
|
||
对于 UEFI 引导的系统，此时需要跳转 BLFS 安装 GRUB。为避免过早地陷入依赖地狱，建议仅按照顺序安装以下包：
|
||
|
||
1. [efivar-39](https://www.linuxfromscratch.org/blfs/view/12.4/postlfs/efivar.html)
|
||
2. [Popt-1.19](https://www.linuxfromscratch.org/blfs/view/12.4/general/popt.html)
|
||
3. [efibootmgr-18](https://www.linuxfromscratch.org/blfs/view/12.4/postlfs/efibootmgr.html)
|
||
4. [GRUB-2.12 for EFI](https://www.linuxfromscratch.org/blfs/view/12.4/postlfs/grub-efi.html)
|
||
|
||
这对于引导系统来说已经足够用了。如果需要的话可以再之后再补上文档等其他附加选项。
|
||
|
||
- [10.2. Creating the /etc/fstab File](https://www.linuxfromscratch.org/lfs/view/stable/chapter10/fstab.html)
|
||
|
||
可以使用 `arch-install-scripts` 提供的 `genfstab` 偷懒。
|
||
|
||
> [!IMPORTANT]
|
||
>
|
||
> 不同于常见的发行版，LFS 需要在 `/etc/fstab` 中指定一系列虚拟文件系统，如果不这样做的话会导致无法启动。
|
||
|
||
- [10.3. Linux-6.16.1](https://www.linuxfromscratch.org/lfs/view/stable/chapter10/kernel.html)
|
||
|
||
内核配置是整本 LFS 书中最具有挑战的环节。对此我可以总结出几点建议：
|
||
|
||
- 复刻并裁剪现有配置
|
||
|
||
如果将要使用正在构建的 LFS 系统的机器和 Host 完全相同，并且内核版本相同或相近，可以将 Host 现在运行的内核的配置文件搬过来，同时仅启用当前 Host 加载的内核模块，这将极大地减小配置难度和缩短构建耗时：
|
||
|
||
在 Host 上运行：
|
||
|
||
```bash
|
||
# 进入内核源码目录
|
||
cd /path/to/lfs/sources/linux-6.16.1
|
||
|
||
# 导出当前内核配置（如果 Host 有 /proc/config.gz）
|
||
zcat /proc/config.gz > .config
|
||
```
|
||
|
||
在 chroot 环境中运行：
|
||
|
||
```bash
|
||
# 进入内核源码目录
|
||
cd /path/to/lfs/sources/linux-6.16.1
|
||
|
||
# 裁剪配置
|
||
make localmodconfig
|
||
```
|
||
|
||
如果内核版本不一致，会在 `make localmodconfig` 时出现很多交互选项，建议全部保持默认，或使用 `make olddefconfig` 来自动处理。
|
||
|
||
在此之后，仍建议按照 LFS 书中的指示检查和调整配置选项。
|
||
|
||
- 参考 Host 的内核配置
|
||
|
||
即使不打算直接使用 Host 的内核配置，Host 加载的内核模块也能为 LFS 内核的配置提供很好的参考，例如当一个门类下有很多并列且可选的选项时，可以优先启用 Host 当前加载的模块对应的选项。
|
||
|
||
- BLFS 要求的内核配置
|
||
|
||
除 LFS 书中列出的内核配置选项外，BLFS 中单独列出了所有涉及的包需要的内核配置选项，建议在配置内核时参考 [BLFS Index of Kernel Settings](https://www.linuxfromscratch.org/blfs/view/12.4/longindex.html#kernel-config-index) 一节，确保启用了所有必要的选项，否则后续可能需要多次重新编译内核。
|
||
|
||
- 对于 NVIDIA
|
||
|
||
如果之后会安装闭源的 NVIDIA 驱动程序，则不建议在内核中启用 nouveau 驱动，因为这会导致闭源驱动无法正常工作，后续禁用 nouveau 将会是额外的工作量。
|
||
|
||
- `<*>` or `<M>`
|
||
|
||
对于大多数选项，建议选择模块化（M）而非内置（\*）。这将显著减少内核体积，并且提高灵活性。但有几种情况例外，例如：
|
||
|
||
- 引导相关的选项（例如 EFI 支持）必须内置，否则无法引导。
|
||
- 一些必要的文件系统（例如 ext4）建议内置，否则可能无法挂载根文件系统。
|
||
|
||
也有必须模块化的情况，例如：
|
||
|
||
- 需要固件支持的驱动程序（如 i915），除非使用 initrd 或将固件内置到内核中。
|
||
|
||
- [10.4. Using GRUB to Set Up the Boot Process](https://www.linuxfromscratch.org/lfs/view/stable/chapter10/grub.html)
|
||
|
||
强烈建议使用 PARTUUID 和 UUID 替代传统的 `/dev/sdXN` 设备路径以及 `(hdM,N)` 来指定 `/boot` 分区和根分区。
|
||
|
||
另外，如果将外置存储设备（如 USB 硬盘）作为根文件系统，建议在 GRUB 配置中添加 `rootdelay=10` 或 `rootwait` 参数以防止启动时找不到根文件系统。
|
||
|
||
> [!NOTE]
|
||
>
|
||
> UUID 和 PARTUUID 可以通过 `lsblk -o NAME,FSTYPE,UUID,PARTUUID` 查看。
|
||
|
||
> [!NOTE]
|
||
>
|
||
> UUID 指的是文件系统 UUID，GRUB 需要具备读取对应文件系统的能力才能识别 UUID。而 PARTUUID 指的是分区 UUID，不依赖文件系统。
|
||
|
||
## BLFS
|
||
|
||
绝大多数的建议都已在 LFS 部分提及，这里只做少数补充：
|
||
|
||
- 阅读顺序
|
||
|
||
BLFS 并不像 LFS 那样有线性的章节顺序，但仍建议先顺序阅读直到 [After LFS Configuration Issues](https://www.linuxfromscratch.org/blfs/view/stable/postlfs/config.html) 章节**结束**再按自己的需要安装各种包。
|
||
|
||
- [About Firmware](https://www.linuxfromscratch.org/blfs/view/stable/postlfs/firmware.html)
|
||
|
||
一个偷懒的方法是把 Host 的 `/lib/firmware` 目录复制到 LFS 的对应目录下：
|
||
|
||
```bash
|
||
cp -av /lib/firmware $LFS/lib/
|
||
```
|
||
|
||
其中 `-a` 选项会保留符号链接和文件权限等信息。
|
||
|
||
- [Mesa-25.1.8](https://www.linuxfromscratch.org/blfs/view/stable/x/mesa.html)
|
||
|
||
此处记录使用 Intel iGPU（i915）和 NVIDIA dGPU（NVIDIA 专有驱动）的混合显卡系统时的配置方法：
|
||
|
||
```
|
||
meson setup build \
|
||
--prefix=$XORG_PREFIX \
|
||
--buildtype=release \
|
||
-D platforms=x11,wayland \
|
||
-D gallium-drivers=iris,llvmpipe \
|
||
-D vulkan-drivers=intel,swrast \
|
||
-D valgrind=disabled \
|
||
-D video-codecs=all \
|
||
-D libunwind=disabled \
|
||
-D glvnd=enabled
|
||
```
|
||
|
||
其中：
|
||
|
||
- `-D gallium-drivers=iris,llvmpipe`：
|
||
- 不包含 NVIDIA 相关的参数，因为 NVIDIA 专有驱动自带完整的 OpenGL 支持，不需要 Mesa 提供。
|
||
- 同时启用 llvmpipe 用于 OpenGL 上下文中的软件渲染以防万一。
|
||
- `iris` 用于 Intel 显卡。对于较新（Gen 8 及更新）的硬件，`crocus`（适用于 Gen 4 到 Gen 7）和 `i915`（更老）用户态 OpenGL 驱动已被废弃，不应再使用。注意此处的 i915 和内核中的 i915 内核驱动是不同的东西。
|
||
- `-D vulkan-drivers=intel,swrast`：
|
||
- 启用 Intel iGPU 的 Vulkan 支持。
|
||
- 同时启用 Vulkan 上下文中的软件光栅化驱动 swrast 以防万一。
|
||
- `-D glvnd=enabled`：启用 GLVND 支持以便和 NVIDIA 专有驱动兼容。libglvnd 需要[在 GLFS 书中安装](https://glfs-book.github.io/glfs/shareddeps/libglvnd.html)。
|
||
|
||
- [Qt-6.9.2](https://www.linuxfromscratch.org/blfs/view/stable/x/qt6.html)
|
||
|
||
此版本的 Qt 在构建时可能会出现错误，日志的一部分如下：

原因是源文件显式包含了多余的 moc 文件，和自动生成的元对象代码冲突，导致重复定义。出问题的源文件有两个，可以通过以下命令修复：
|
||
|
||
```bash
|
||
sed -i -E 's|\s*#include "moc_.*|// &|g' qtpositioning/src/plugins/position/geoclue2/qgeopositioninfosourcefactory_geoclue2.cpp qtpositioning/src/plugins/position/geoclue2/qgeopositioninfosource_geoclue2.cpp
|

```
