hi,

so in order to quantify exactly what should be on the minimal install set :

Questions;

Hi Karanbir,

Do you know the RHEL 6 CD called "Network Install and Recovery Disc"? (222 MB)

My suggestion would be to do the same.

Best regards,

Morten

• support install from optical media

• support install from usb disk

• install as native platform

• install to Xen domU
• install to kvm VM

• Functional on post-install

• firstboot ( for hooks etc that people put in )
• yum with the standard centos repos
• sshd
• selinux
• functional dhcp client
• functional ipv6 stack + ipv4 stack
• iptables and ip6tables

https://nazar.karan.org/cgit/bluecain/tree/ks-minimalC5-64.cfg is my idea of a minimal install. It lacks xen/kvm support however which probably should be in.

Questions;

• What else should added in ?

if we go with "minimal", that would be a reasonable list. if we go with "server", I'd add mysql, apache, postfix + basic php . maybe even dovecot + php-imap.

• Should we remove some more excess ?

• what is the thinking on lsb state for this media ?

/me never really cared about lsb* packages

• Finally, I am conflicted on the idea of dropping the gui installer

completely. On one hand, we could claw back serious disk space - on the other hand, it drastically changes the install experience. Tbh, the install experience is a bigger deal. But worth pointing out.

Please don't. The installer is the first major experience and even real professionals do not need/use it, the rest of the universe uses it as a first factor for decision.

A list from my kickstarts :

+ ntp + wget and/or links + rsync + telnet (as a test tool)

And the problem that the text interfance does not support LVM (at least in 5, I don't know if they added that in 6) and there are problably other features that are only in the GUI interface.

The real constraint should be what fits on a single CD. Ideally, the GUI installer including the reverse-vnc functionality would all be there if it fits. It would be even better if you could make that come up working without any local questions in a machine with one connected network cable and local dhcp. This would be mostly for people who don't have pxe/kickstart infrastructure in the location where the install is being done, but to make the circle complete it should support kickstart with an http url on the command line or perhaps added in a modified USB version, and it should be possible to kickstart into the same set of packages from the full distribution with a matching package list.

I'd want it to function as the 'rescue' media as well as install, so include anything else needed for that functionality. I've sometimes needed to fdisk my own partition layout to get things the way I like for a raid configuration, so include that. Others have already mentioned network copying tools: ftp/scp/rsync/wget, etc., and you would need network setup and test tools (mii-tool, ethtool, route, ip, ping, etc.) if they aren't already needed for the installer.
