'make fetch' and 'make installer_release' are the commands you issue, and you'll make an ISO, as I recall. You will need to package up the applications you want on the install CD and put them in the appropriate place to get them included.

Re: How to rebuild LiveCD
I think his question is essentially something I'd asked long time ago - how to create a LiveCD from a pre-installed environment. Sort of like the FreeSBIE (FreeBSD), Linux, or NetBSD live CDs floating out there. Basically, you have a running environment with configured applications such as Firefox and OO, and you want to convert it to an ISO, which when booted gives you all the apps you had installed on your HDD. The DFLY "release" process I think is geared towards creating an "installation" live CD. It will boot but won't be a ready-to run GUI environment just like your HDD deployment but rather a live CD from which you can install the applications you chose to include when creating this custom "release" CD. As far as I remember Matt said that you can create a FreeSBIE-style live CD yourself but you have to do it manually and also Dfly doesn't support a compressed filesystem over the ISO so that your CD will be limited to 700MB of software, not 2-3GB like FreeSBIE. NetBSD have a script in pkgsrc called "livecd" but I think it's deprecated at this point. If the live CD situation for Dfly has changed then please let me know. I'd very interested in experimenting with Dfly and maybe create a desktop oriented live CD like FreeSBIE. It's a great marketing tool for Dfly.

Re: How to rebuild LiveCD
The DragonFly /usr/src/nrelease process can be used to build any live-cd, it doesn't have to be an install-cd. It's very modular but you need to play around with it to find the right combination of base packages to include before you roll in the custom changes that it wouldn't be able to handle. -Matt

I'm with Matt on this one. If someone does such a thing, please integrate it into the nrelease framework. Something like "make gui release" or so. In fact, I hacked a bit on it once, and the main issues up to the point where I got (I think it was starting up X from the CD but not much more) were iirc: 1) That with pkgsrc it seemed impossible to have meta packages on a local drive and have it download their dependencies from some mirror. 2) Adjusting to the current CD setup where most available disk space is read only. A real effort would probably include laying out filesystems differently. I also think it should be a live DVD then. But it depends on the packages you'd want on it, of course.

Re: How to rebuild LiveCD
OK, that answers part of the question - we can create live CDs. How about the compressed filesystem? Does Dfly have anything similar to SquashFS (Linux) or cloop2 (FreeBSD/NetBSD) so we can cram a lot of software in the 700MB ISO limit? Thanks in advance.

:1) That with pkgsrc it seemed impossible to have meta packages on a :local drive and have it download their dependencies from some mirror. : :2) Adjusting to the current CD setup where most available disk space is :read only. A real effort would probably include laying out filesystems :differently. : :I also think it should be a live DVD then. But it depends on the :packages you'd want on it, of course. : :Sascha Not sure whats going on w/ pkgsrc, but we've already got the read-only issue mostly dealth with. The CD is basically just a starting image and we overload the bits that we want to make R/W using MFS mounts. -Matt

A real effort would probably include laying out filesystems > differently. I'm very interested in efforts along these lines myself. I've gone through some issues with CD creation. I do have something somewhat like what you are all talking about, but for a different purpose. I've hacked together a CD that Dragonfly "runs directly on". Really, it mounts an MFS root, and then copies from or maps the CD onto that. I have a methodology for caching frequently used binaries into the memory filesystem, but my goal was not to lay out filesystems any more differently than I had to and I'm not sure it's even necessary. My CD is primarily for running servers (especially firewalls) where you really want some solid rootkit/rogue SA protection and/or you want to upgrade many multiple servers all as a single unit. I doubt it would be very good for desktop use. (That doesn't mean I'm not interested in desktop dragonfly CDs, I'd love to see an effort for that and would even help where I could.) As a related point, I really want to contribute this server CD back, but I'm concerned it's not good enough for the standards that many of you have for these things; it's really not clean yet according to my own standards. The issues I see at the moment are: * I had to modify /etc/rc and insert a small shell script into the startup process. * I've hacked the installer quite a bit (even found a bug) in ways I doubt very much are compatable with the direction the installer is going. (I just wrote my extra code in C, for example). * It's not clear how supported an MFS root filesystem is. * Trying to get pkgsrc packages on it proved to be extremely problmatic. It was easier just to make an anonymous read-only FTP archive of pre-built packages and populate that from a development box. The other issue with this is that packages are faster moving targets than Dragonfly is (even with the HAMMER hacking). In fact I'm really not sure it is possible to have applications that BSD users won't be upgrading as soon as they get them anyway. Just consider the rash of Firefox upgrades a while ago as an example. * The process for making one of these CDs is in a bourne shell script and -not- in the /usr/src/nrelease/Makefile. It does use "make" whereever possible to stay compatable with what goes on in development. However, I am not a Makefile guru, just a humble power user. You need to be a guru to deal with BSD Makefiles these days, and I am very leary of changing that Makefile when I'm not a guru and when I don't have (or really want) commit access. That last point is really my show stopper. I'd love to work on the current /usr/src/nrelease/Makefile system, but there's no clear and comprehensive documentation that I have found that would aid me in making changes that would be acceptable to the community. I've been told it doesn't exist. Maybe I'm confused? > I also think it should be a live DVD then. But it depends on the > packages you'd want on it, of course. This would be great, but can DFly boot off a DVD?

The issues I see at the moment are: The first person to complain about it not being up to standards gets to be the one who brings it up to standards. Seriously, though, please share. I've wanted a CD/DVD that does this for a long time.
