你的脚本已经非常接近完成且非常专业，涵盖了大部分的配置项，尤其是在 `bcc`, `eBPF`, `Cilium`, `调试`, `BTF` 等功能上。然而，正如我们之前讨论的，**`initramfs` 无法引导** 的问题可能是由于 **缺少块设备驱动** 或 **文件系统模块**。因此，结合你的需求，我已将 **文件系统支持** 和 **块设备支持** 的模块添加到脚本中，并且包括了 `dracut` 生成和验证 `initramfs` 的步骤。
### 修正后的完整脚本：

### 脚本要点：
1. **文件系统支持**：加入了 `EXT4` 相关的支持，以确保可以挂载根文件系统。
2. **块设备支持**：加入了 `VIRTIO_BLK`, `NVME`, `AHCI`, `SCSI` 等常见块设备驱动。
3. **`initramfs` 生成和验证**：确保生成时包含关键驱动，并通过 `dracut` 强制打包必要模块。
4. **内核编译后步骤**：重新编译并确保 `initramfs` 包含所需模块，验证模块是否存在。
### 下一步：
你可以执行以下命令，按照步骤进行编译和验证：
```bash
make olddefconfig
make -j$(nproc)
sudo make modules_install
sudo make install
# 重新生成并验证 initramfs
sudo dracut -f /boot/initramfs-$(
```
#!/bin/bash
set -e
# 确保在内核源码根目录运行
if [ ! -x scripts/config ]; then
echo "Error: 请在内核源码根目录运行"
exit 1
fi
config_exists() {
grep -qr "^config $1" . || return 1
}
try_enable() {
if config_exists "$1"; then
echo "启用 CONFIG_$1"
scripts/config --enable "CONFIG_$1"
else
echo "跳过 CONFIG_$1（不存在）"
fi
}
try_module() {
if config_exists "$1"; then
echo "模块化 CONFIG_$1"
scripts/config --module "CONFIG_$1"
else
echo "跳过 CONFIG_$1（不存在）"
fi
}
