引言

Fedora-CoreOS特有的RPM包如下(忽略版本信息)：

bind-libs-32:9.16.21-1.fc35.x86_64
bind-license-32:9.16.21-1.fc35.noarch
bind-utils-32:9.16.21-1.fc35.x86_64

fwupd-1.6.4-1.fc35.x86_64

podman-3:3.4.0-1.fc35.x86_64
runc-2:1.0.2-2.fc35.x86_64
skopeo-1:1.5.0-2.fc35.x86_64
systemd-resolved-249.4-2.fc35.x86_64
toolbox-0.0.99.2^3.git075b9a8d2779-4.fc35.x86_64
util-linux-core-2.37.2-1.fc35.x86_64

那么就需要将src源玛RPM包在CentOS-Stream-9上进程rpmbuild生成二进制包，这是最简单的方法。

二进制RPM包的重构

标准重构流程

构建过程简单可以概括为：

# 1. 下载源玛包（在Fedora虚拟机上或者指定dnf repo地址）
dnf download --source bind
# 2. 将源码包拷贝到用于构建的目标虚拟机或者服务器上
# 3. 安装源码包
rpm -ivh bind.xxxxxx.src.rpm
# 4. 安装依赖，注意，需要使能crb
cd ~/rpmbuild/SPEC
sudo dnf builddep --enablerepo=crb bind.spec
# 5. 如果依赖不能够满足，需要下载不满足的依赖，编译并安装
# 6. 编译
rpmbuild -bb bind.spec

bind

按照标准重构流程即可，这将生成以下RPM二进制包(忽略版本信息)：

conmon

依赖go-md2man，需要下载

golang-github-cpuguy83-md2man-2.0.1-1.fc35.src.rpm
    依赖于： golang-gopkg-russross-blackfriday-2-2.1.0-3.fc35.src.rpm

其中golang-gopkg-russross-blackfriday能够顺利安装，但是，重新编译后RPM提供的能力发生了变化(命令dnf provides查看)

• 在Fedora中提供的叫做：golang(github.com/russross/blackfriday/v2)
• 在CentOS-Stream中提供的叫做：golang-symlink(github.com/russross/blackfriday/v2)

所以需要修改golang-github-cpuguy83-md2man.spec文件。

rpmbuild后生成的RPM包有：

├── noarch
│   ├── compat-golang-github-cpuguy83-md2man-2-devel-2.0.1-1.el9.noarch.rpm
│   └── golang-github-cpuguy83-md2man-devel-2.0.1-1.el9.noarch.rpm
└── x86_64
    ├── golang-github-cpuguy83-md2man-2.0.1-1.el9.x86_64.rpm
    ├── golang-github-cpuguy83-md2man-debuginfo-2.0.1-1.el9.x86_64.rpm
    └── golang-github-cpuguy83-md2man-debugsource-2.0.1-1.el9.x86_64.rpm

注意，安装golang-github-cpuguy83-md2man-devel-2.0.1-1.el9.noarch.rpm会提示需要golang(github.com/russross/blackfriday/v2)，直接不安装就行了，转而安装compat-golang-github-cpuguy83-md2man-2-devel-2.0.1-1.el9.noarch.rpm.

然后rpmbuild conmon就可生成：

└── x86_64
    ├── conmon-2.1.0-2.el9.x86_64.rpm
    ├── conmon-debuginfo-2.1.0-2.el9.x86_64.rpm
    └── conmon-debugsource-2.1.0-2.el9.x86_64.rpm

container-selinux

安装标准流程构建即可，生成：

└── noarch
    └── container-selinux-2.180.0-1.el9.noarch.rpm

containerd

containerd依赖的就非常的多了：

‘golang(github.com/containerd/aufs/plugin)’

需要安装的包为：golang-github-containerd-aufs-1.0.0-2.fc35.src.rpm.

coreos-assembler的适配

锁定kernel

最新的cosa锁定了内核版本，如下：

rpm-ostree version: 2022.5
Previous commit: fa1820378f0e7f70420d6d05c164fd00e2c89006f290fa566171c6ed6ad2bbfe

  Packages matching name and arch (1):
  kernel-5.15.13-0.el9.x86_64 (fedora-coreos-pool)

这在文件coreos-assembler/build.sh中有：

 37 install_rpms() 
 38     local builddeps
 39     local frozendeps
 40
 41     # freeze kernel due to https://github.com/coreos/coreos-assembler/issues/2707
 42     frozendeps=$(echo kernel,-core,-modules-5.15.18-200.fc35)

锁定systemd

以上两个问题通过修改manifest-lock.overrides.yaml文件即可修改。

cosa build错误

提示的错误为：

Skipping file /usr/etc/grub.d/10_reset_boot_success from checkout
Skipping file /usr/etc/grub.d/12_menu_auto_hide from checkout

原因是catatonit和podman-catatonit冲突了。

ISO装机启动服务失败

参见下图

dbus-broker.service

dbus-broker.service依赖于dbus.socket.

发现/tmp没有写权限。2022-03-17 17:08
没有挂载，见tmp.mount，删除了systemd中对 tmp.mount注释的补丁并重新编译systemd，见提交 a76940。

coreos-installer的问题

coreos-installer后重启失败

因为重构后的coreos使用coreos-installer安装后，重启无法正常启动，卡住的位置：

systemd[1]: Startup finished in 1.726s (kernel) + 0(initrd) + 2.722s (userspace) = 4.449s

卡住一段时间后会自动再次重启，然后又卡在这个位置。那么我们先查看正常情况下的文件系统。
