为什么ubuntu server 的installer比debian stable 的installer卡很多?

debian-8.3.0-i386-netinst.iso
ubuntu-14.04.4-server-amd64.iso
测试环境:VirtualBox
安装镜像放在tmpfs上

比较懒,随手找的镜像测试
不过amd64除了多费点内存之外应该是比i386更快吧?
具体现象:
有一个一闪而过,sda什么的失败了,看不清
我这里ubuntu server的安装界面经常性的只有背景颜色,实机内的CPU指示显示guest的CPU可能几乎占满
debian stable在虚拟机内完全正常

如果真的有必要,我试着导出日志文件(因为是installer环境,没办法直接导出,要稍微折腾)

1. https://wiki.debian.org/DebianInstall#D ... install_CD
This network install ISO (called "netinst") contains just enough packages to install a very basic Debian system. During the install procedure only the required packages are downloaded from the Internet, making it more efficient overall. A netinst iso image is around 180 MB.
netinst 可以視為 最小安裝

2. ubuntu 也有最小安裝 mini.iso
https://help.ubuntu.com/community/Insta ... /MinimalCD

3. 你可以拿 mini.iso 來跟 netinst.iso 較競 比較公平

mini.iso和 netinst.iso比根本不公平
debian也有mini.iso
http://ftp.nl.debian.org/debian/dists/j ... s/netboot/
mini.iso是netboot,类似无盘主机那样(看介绍貌似是吧,具体不太懂,也没条件去试,但我可以肯定的说它与netinst.iso是两回事)
貌似ubuntu本身并没有严格意义上的netinst.iso,只有服务器版和桌面版,或者alternate(这个是桌面版但安装风格类似debian的installer)
介绍:https://www.debian.org/distrib/netinst
Network boot
一栏的介绍

这次和您的讨论激发我对server版的兴趣
结果在虚拟机离都貌似各种异常,Debian的installer正常
所以才我才发了这个帖子.

听说Ubuntu的社区交流社区比Debian更友好,我想部分原因是真正值得认真讨论的问题(故障)比Debian多
个人看法哈,欢迎提出不同看法交流

我发这贴的意思是,第一次碰到连虚拟机内都异常的发行版.
以前各种Ubuntu版本和Debian在虚拟机都正常
Ubuntu server让我感到惊讶

1. https://help.ubuntu.com/community/Insta ... mmended.29
Ubuntu 15.10 "Wily Werewolf" 40MB
The minimal iso image will download packages from online archives at installation time instead of providing them on the install media itself.

2. https://wiki.debian.org/DebianInstall#D ... install_CD
During the install procedure only the required packages are downloaded from the Internet, making it more efficient overall. A netinst iso image is around 180 MB.
Downloading packages at install time reduces the size of the iso image to approximately ~40MB depending on architecture (see below), as well as providing only the packages needed for installation.

3. http://releases.ubuntu.com/15.10/
ubuntu-15.10-server-amd64.iso 632M

4. mini.iso 與 netinst.iso 都一樣 安裝時 才從網路下載套件 不預存在 iso 裡

5. mini.iso 跟 netinst.iso 的大小差距 與 netinst.iso 跟 server-amd64.iso 的大小差距
Ubuntu mini.iso 40MB
netinst.iso 180 MB
server.iso 632M

6. 比較公平 本身就是一種相對的用詞 不是 絕對的結論

2. 這一篇 給 Ubuntu 的社区 與 Debian 的社区 作一個比較
http://www.datamation.com/open-source/d ... you-2.html
Communities
For users who may become involved with developing, Debian's and Ubuntu's communities may also be a factor in their choice.
2-1. Debian
Debian is famous -- even infamous -- for discussing everything in great detail. Especially contentious issues can even go to a general vote.
In recent years, Debian appeared to mellow, but the discussion can still sometimes become a free-for-all. In the past, Debian has been described as a hostile environment for women, and, just recently, the debate on replacing init with systemd became so intense that a couple of veteran developers resigned rather endure abuse.
At the same time, Debian is a meritocratic democracy, with all official maintainers voting on the Debian Leader and other issues. Although appointed positions can sometimes be a source of power, in general Debian officials lead more by suggestion and diplomacy than direct command.
2-2. Ubuntu
Ubuntu contrasts with Debian in that it has a Code of Conduct for community interaction. Until recently, Ubuntu's community manager was Jono Bacon, who literally wrote the book on The Art of Community, and made considerable effort at conflict resolution. In addition, a Community Council and Technical Board is partly elected every year.
However, this democratic appearance is not quite what it appears. Ubuntu's founder, Mark Shuttleworth, sits on both governing boards permanently, and casts the deciding vote. Shuttleworth -- and, at times, his Canonical representatives -- also have veto power over the community, which in the past has caused several user revolts.

英文很烂所以这次就没看英文介绍
根据以前看的英文介绍结合这次我下载了ubuntu和debian的mini.iso 对比发现
mini.iso依赖于局域网
相当于从局域网的服务器上获取完整iso文件,自身却几乎不提供任何安装能力
如果没有局域网,ppp拨号甚至都无法实现
netinst.iso虽然是也是网络安装,但自身提供更加完善的功能,比如可以通过pppoe拨号来实现网络安装
并且在完全没有网络的情况下它也能安装一个基本的可启动的系统.

果然不是浪得虛名
