from the making-your-own-mark-on-Linux dept.
Jason Tilke asks: "I recently read an article which discusses HP's LinuxCOE v4. We've been wanting a system to make rolling out custom but standardized systems (in terms of package selection) and LinuxCOE seems to fit the bill. Are there any alternative that'll spit out custom ISOs which our non-technical staff can use to install a complete Linux system? Has anyone had any positive/negative experience with LinuxCOE? Are there any precautions/steps we should take to prevent us from tripping over our new changes?"

It's been easy to make a reformed version of Fedora, and the various Redhats, for some time. There hasn't been a GUI tool for it before, and they haven't called it a respin, but they've been there.
See here [techonthenet.com] for example. It tells how to generate new ISO images from the original ISOs and updated RPMs. I've personally used the tools to build stripped down versions of Redhat/Fedora that include everything I need, but on a single CD. You can also include a kickstart file on the CD so that you can give a "linux ks=cdrom" at the initial install prompt to run a fully automated install. I don't think Redhat would have ever been as useful to corporations had it not had this option. Why install old RPMs? Install the OS with the latest, greatest everything.

Fedora Unity have been doing respins for quite a while. The Revisor [fedoraunity.org] tool makes it possible to this with hardly any trouble at all.
PCtech [pctech101.com] used revisor to create an 11CD install set because although Fedora 7 could be obtained as an installable LiveCD and then packages added over the network, some people didn't have the bandwidth or a DVD, so needed the CDs.

Sure, it's been easy to swap a few things around in many distributions' installation ISOs for a long time, but it hasn't been very "easy" except for a few distros built specifically for modification by end users. Fedora 7 provides a nice easy GUI for it :)

I'm seeing some comments saying "this is hard and will always be hard" or suggestions to use this-or-that third party tool. But I'd really, really encourage you to take a look at Revisor from the Fedora Project.
Fedora doesn't really produce a Linux distribution anymore -- they produce a well-integrated Linux repository and the tools to make distribution media "spins" (live disc, installation disc, repository subset) from that repository or to do installations directly from that repository.

"AutoYaST [novell.com] allows unattended and automated installation. With AutoYaST, administrators can create a consistent baseline configuration for new installations in large or expanding deployments. In addition to AutoYaST, other installation methods include PXE Boot, CD-ROM, NFS, CIFS/SMB, HTTP, FTP, and the Service Location Protocol (SLP), which allows autodetection of install servers."

Have someone do it for you.
Seriously, package integration (or removal) is NOT easy, in general, and trying to get it foolproofed is a major headache. What do you do if someone wants to "easily" remove some useless stuff he never uses (expat) but not the programs that depend on it?
You will eventually reinvent all the huge and occasionally buggy installers everyone's got, or something equivalent.
It's not going to be easy. It might be worth it, but think about it first; do you really need that level of custo

Your warnings are based on a misunderstanding of what the OP wants. The OP wasn't looking for a foolproof system to remaster foolproof CDs, but a system to remaster foolproof CDs. Note the extra foolproof in the first case.
You also seem to think that there aren't already decent tools for making live/install CDs, when there are several in existence. No reinventing of installers is necessary.

Take a look at
Knoppix Remastering [knoppix.net].
In a former life, I used to build custom embedded Linux distros
as the base platform for other company projects; Knoppix makes
it soeasy, if I hadn't already moved on from that job,
it would have sent me to the unemployment line.
Actually, I exagerate a tad there - Knoppix makes it almost trivial to
get a customized Debian-based system down to the 40-50MB range; On my most
challenging project, I managed to get a stable system running custom
builds of X and Mozilla to fit on a 16MB flash disk. But presuming you
don't have quite such minimalistic hardware requirements, Knoppix
makes the task a breeze. Just unpack it, chroot into it, "apt-get remove"
whatever you don't want and build whatever else you do, and roll it back
into a cloop'd iso. C'est fini.
For comparison, I usually prefer to run Slackware as my normal Linux
distro, and looked into Slax [slax.org] before
Knoppix. For some tasks you might find it easier to work with, as it
uses a more modular approach, but I found that far more limiting
and inconvenient if you want to make fine-grained tweaks or even just
alter configuration details without swapping out whole packages.

Knoppix is good at this, but I didn't have the same experience as the parent. Either I did something to munge apt, or, well, SOMEthing, but I couldn't get one to boot under 100MB or so. I didn't have a lot of patience with what I removed or included, but once, due to dependencies, it started to remove some really base packages, and I got fed up.
In my experience, if you really need to get small, just use DamnSmallLinux. Tack on the apt and actual gnu utils dsl packages, and you're in business, and there's

I find that, for the most part, apt will warn you if you try to remove something
important... But not always. When in doubt about one of the packages it shows,
try checking what it does with something like:
dpkg-query -W --showformat='${Installed-Size} ${Package} ${Description} ${Status}' packagenamegoeshere

I've done this a few different ways over the years. At first I used a system called systemimager that allows you to have minimal install media (small iso or floppy) and pull the image from a server during install. This is nice in that it catches EVERYTHING on the filesystem, but can be a pain to admin/update later and doesn't work without a server available. It also doesn't let you drop to the installer's UI for allowing the user to choose options such as partitioning as that needs to be in the script as well. I have since moved to managing machines using custom install processes/ISOs and local package repositories and like it much better.
I've also used SuSE's autoyast which records package selection and config settings that you can then use as input for subsequent installs. This is well documented. I also used RedHat's kickstart awhile ago but didn't do too much with it.
Most recently I've created custom ISOs for Ubuntu using the preseed mechanism. This requires editing a few text files specifying such settings as network config, default desktop, etc. There is a way to put your extra packages right on the CD but I just have a firstboot script that updates from a local repository using a list of package names to install. Metapackages are also useful here as you can make a metapackage that just depends on all the packages you want and update that whenever you wish all the existing or new machines to get new packages.
All of these options are fairly well documented but may take some trial and error work to get things the way you want. It really depends on the distro you are using.

After that just make a fake package that depends on all of them and includes the relevant customisation. Not very difficult. It has one disadvantage - it does not make the install fully automatic. You have to answer questions which may lead to inconsistency.
Unfortunately, debian still does not read everything in every package out of the debconf database so even prepopulating it will not always help. So unless you are doing 50+ it is cheaper to make a custom package, but still hire someone to press enter and

You may want to check out Gentoo Catalyst. Before I get flamed about having to watch code compile etc... Let me just say that this tool allows you to completely customize your install stages, and you can make a stage 3 installer which only uses binary packages.
For a large scale roll out this tool is ideal. It is not easy or idiot proof on the admin side, but once you make your custom ISOs, it will be painless on the user side.

You can get a program for Ubuntu called "Reconstructor", which makes it literally drag-and-drop to make ISOs of custom Ubuntu systems. You just optionally specify a desktop theme and startup picture, make a list of packages you want it to come with, and it gives you a nice ISO. The alternate install CD of Ubuntu is supposed to make it easier to rollout systems but I'm not sure how.
