Yes, substantially. livecd-creator basically sets up a chroot on the system it's running on and interprets the live image kickstart itself to install a bunch of packages and do a bunch of modifications to that environment, then converts that environment into an image file. livemedia-creator works by running an anaconda install into an environment, feeding the kickstart to anaconda rather than interpreting it itself, and then converting the resulting environment into an image file. It was originally *intended* that the environment would be a virtual machine, but that turned out to be fundamentally incompatible with how Koji works, so lmc now has a '--no-virt' mode where it uses a fairly new anaconda feature that lets you run an install into a directory. > Or > harder to use ? In a way, it is. With livecd-creator, you can quite easily run an image build from your regular Fedora system in a way which is virtually identical to how Koji does/did livecd-creator builds, so what you get is very similar to an 'official' live image. It's rather harder to do this with lmc. The way Koji uses lmc is it sets up a mock chroot, then uses lmc --no-virt within the mock chroot. If you want to build a live image the same way 'official' Fedora live images are built, you have to either set up your own Koji deployment (which is its own whole nest of rats) or recreate this process manually (or write a script to do it): you have to create a mock chroot, install the necessary packages into it, copy a flattened kickstart file into it, then run the compose inside the chroot and get the resulting image file out of the chroot. It's all possible, and not that hard once you've done it a couple of times, but it's substantially more of a faff than just pulling a one-line 'livecd-creator' command out of your command history. Your *other* choice is to use lmc's virt mode, which you should be able to use from your regular desktop without any special preparation. However, that doesn't work the same way our official image builds work so it's possible it might somehow behave differently and give you images with some important difference from the official ones (or just be broken entirely), and some people have had trouble getting it to work properly. Including me - every time I've tried to use it, it's gone wrong somehow (I haven't tried it lately since I figured out how to use the --no-virt mode in mock, though). One of the things on my List Of Side Projects To Work On If I Ever Get Time is a sort of koji-lite wrapper script which would let you run a single command to do the '--no-virt build in a mock chroot' thing on a typical Fedora system, but I've just never got around to it yet. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
