两个实现方案
A. 将tms整合到ubuntu里,制作一个自己的发布盘和安装盘。
B. 自己安装ubuntu, 另外再通过安装包安装tms。
优先实现方法A. 这里面也分2种,一种是利用现有工具,一种是按照ubuntu官方的定义,自己写脚本,编辑配置文件,定制安装盘。
现状:
tms是通过母盘复制的。
tms本身是shell脚本安装到ubuntu里的。
支持系统: ubuntu 16.04
tms的实际安装情况:
需要安装java sdk;需要安装usbkey驱动;需要安装tms的java程序; 需要修改配置文件。自动挂载xT硬盘(系统分区时已经解决)。
以上这些步骤都可以通过shell命令自动完成。usbkey安装需要联网。
BFT的安装情况:
联网,shell脚本自动安装
巴克的安装情况:
联网,安装依赖库,安装软件。
需要调研:
是否需要制作deb安装包,才能制作下一步的ubuntu安装盘。
需要的话,就先把tms的deb制作好。
不需要的话,就只需要把相关文件通过shell脚本执行,并在ubuntu的安装盘安装过程中复制到系统既定位置,但是前提是对ubuntu的安装规范及其了解并且可以定制它。
systemback 在vmware上测试通过,据反映,有些只有uefi的新硬件无法启动,为了支持uefi启动,需要将efi的启动分区加入,步骤见下面第3章的systemback部分。
自己通过脚本定制安装内容,在安装BFT的情况下,vmware测试通过。
为了制作完整的tms母盘,需要将tms进行安装并测试其可用性。
大家各自有自己工作任务,时间不充沛,需要大量公司内部沟通,这事要有一个人负责和主导。
这个人要熟悉 tms的母盘安装和验证,了解各种硬件,跟研发有充分沟通。
在vmware上验证通过的安装盘定制方法,需要此人进一步在不同实际硬件上,TMS的各类软件硬件功能上进行仔细而认真的验证。

sudo mount -o loop ubuntu-16.04.1-desktop-amd64.iso /mnt/lp1
检测当前系统是bios还是uefi
test -d /sys/firmware/efi && echo efi || echo bios
A. 安装
sudo add-apt-repository ppa:nemh/systemback
sudo apt-get update && sudo apt-get install systemback unionfs-fuse
sudo apt-get install live-boot -y
sudo apt-get autoremove --purge casper
B. 通过systemback制作live system,然后制作为 systemback.iso
C. 添加uefi分区到 iso ( efi.img 来自 安装盘 extract-cd/boot/grub/efi.img)
cd /home
cat `ls -1 -t syst*.iso|head -1` efi.img >/tmp/live.iso
echo -e "n\np\n2\n\n\nt\n2\nef\nw\n"|fdisk /tmp/live.iso
D. 制作到u盘上。通过netbootin软件或者dd命令。
pv /tmp/live.iso | dd of=/dev/sdb conv=notrunc,noerror
https://github.com/Distroshare/distroshare-ubuntu-imager
其工作原理为:

git clone https://github.com/Distroshare/distroshare-ubuntu-imager
cd distroshare-ubuntu-imager/
./distroshare-ubuntu-imager.sh
可以制作成功,但是没有安装选项。

sudo apt-get update
sudo apt-get install respin isolinux
# 可安装程序。
apt-get install ubiquity ubiquity-frontend-gtk
制作:
sudo respin dist cdfs
sudo respin dist iso cutstom.iso
这样安装完后,iso可以启动可install, 但是安装一半时 install crash.

原代码不能支持比较大的原文件(不能支持单文件大于200G左右, 具体下限不确定),其中一个原因是生成的metainfofile: ctorrent文件过大,程序认为不合理。所以将限制改大即可。

How to create custom Ubuntu install with packages, system settings, defaults?
use the ubuntu preseed for that.
In ubuntu iso you can find it under preseed/ubuntu.seed
Automating the installation using preseeding

Guide to particulars in customizing Ubuntu Installer
https://askubuntu.com/questions/29121/guide-to-particulars-in-customizing-ubuntu-installer?rq=1
For a reference preseed, you might like to refer to installation-guide-i386 which contains the following sample preseed:
/usr/share/doc/installation-guide-i386/example-preseed.txt.gz
- Completely rewrite the packages installed by default, much like minimal installs
- Add a few proprietary applications to the default install list
To provide the list of packages you want installed, you might like to look for the following line:
tasksel tasksel/first multiselect ubuntu-desktop
Where "ubuntu-desktop" can be changed for an arbitrary number of packages or meta packages.
- Automatically install and mount proprietary drivers on install and live session
Other that specifying the packages needed (for the proprietary drivers), I'm not sure how this would be accomplished. As a side note, you "mount" a partition, you "load" a kernel module/driver.
- Edit the default configuration files for applications installed by default
To make those kind of scripted changes, you probably want to look into:
d-i preseed/late_command string ...
Where the "..." can be replaced with arbitrary commands like sed -i for example.
- Specify partitions along with permission
There's a partition section in the example preseed mentioned above.
Ubiquity with preseed
Casper supports preseed and ubiquity can have many values preseeded. Here are some of the variables that can be preseeded relevant to ubiquity:
ubiquity countrychooser/shortlist select US
ubiquity languagechooser/language-name select English
ubiquity localechooser/supported-locales multiselect en_US.UTF-8
ubiquity ubiquity/summary note
ubiquity ubiquity/reboot boolean true
ubiquity ubiquity/poweroff boolean true
ubiquity ubiquity/success_command string ...
Where "..." would contain the same as the late_command mentioned above, success_command is read by ubiquity and late_command by d-i.
参考:
https://askubuntu.com/questions/409607/how-to-create-a-customized-ubuntu-server-iso/409651#409651
系统上可以参考的preseed文件示例。
/usr/share/doc/installation-guide-i386/example-preseed.txt.gz
下载 ubuntu 16.04 iso, 然后修改路径和名称, 执行 customcd.sh
其中可以修改自定义安装的package.
具体是在准备阶段,将deb复制过去。 在chroot的安装阶段进行deb的安装。
下面是个实例,是ctorrent的安装。
# Prepare and chroot
sudo cp /etc/resolv.conf edit/etc/
sudo cp /root/soft/ctorrent_1.3.4.dnh3.3.2-4_amd64.deb edit/tmp/ # add here.
sudo cp /root/install-bft.sh edit/tmp/
....
apt-get install google-chrome-stable yubikey-luks -y
dpkg -i /tmp/ctorrent_1.3.4.dnh3.3.2-4_amd64.deb # add here.
/tmp/install-bft.sh
chmod 755 /etc/rc.local
apt-get autoremove -y
apt-get autoclean -y
最后形成一个 install iso, 可以用于安装。
为了修改preseed文件, 也可以将shell脚本分成2步来执行,
c1.sh; 完成准备, 然后修改preseed脚本。
c2.sh; 形成chroot,然后安装定制pkg, 最后形成iso.

# 2017-July-04 - having difficulties building a custom Live CD that boots from a USB stick
#
# Tried https://nathanpfry.com/how-to-customize-an-ubuntu-installation-disc/, but no joy.
#
# So, reverting to 'base' documentation, I attempted a
# Simple extraction/decompression/re-manifest/compress/make iso image
# based on https://help.ubuntu.com/community/LiveCDCustomization
#
# Could NOT get this to work using genisoimage, even with adaptations from
# https://askubuntu.com/questions/457528/how-do-i-create-an-efi-bootable-iso-of-a-customized-version-of-ubuntu which
# pointed me toward "-eltorito-alt-boot and -e boot/grub/efi.img -no-emul-boot"
#
# 2017-July-05 - success, but only with xorriso
#
# Eventually, Google pointed me to yet another tool to install, xorriso, thanks to
# https://linuxconfig.org/legacy-bios-uefi-and-secureboot-ready-ubuntu-live-image-customization
#
# It works. If anyone cares to propose updates to the script that do not require the 'dd' of isohdpfx.bin
