#235 | fixed | Debathena Live CD installs an initrd that enables compcache. | xavid | xavid |
Description |
debathena / livecd / xavid 19:54 ('I want to be the duke of Chicago.`) Jaunty-compatible live cd is pushed and ready for someone to prod on debuild. If someone other than me wants to try the less-trusted-version, http://debathena-livecd-build.xvm/cds/ debathena / livecd / xavid 19:59 ('Sucks-to-be-you-tastic.`) I guess I'll send mail if no one's particularly up for prodding it now. debathena / livecd / andersk 16:53 (Anders Kaseorg) debathena-livecd-convert runs `update-initramfs -u` from inside the live CD chroot. As it turns out, this results in machines installed using the live CD, such as ozok-the-destroyer.mit.edu, to be fuxx0red in various ways (e.g. compcache is enabled). debathena / livecd / broder 16:54 (Evan Broder) Can you put this on the existing Live CD bug, or open a new one? debathena / livecd / jdreed 16:54 (This zephyr does not necessarily reflect A new one, please. The existing one is a bit too general debathena / livecd.d / jdreed 16:55 (This zephyr does not necessarily refle I blame the person who opened the ticket for not picking a better subject line debathena / livecd.d / broder 16:55 (Evan Broder) Haha debathena / livecd / xavid 16:56 (“Werewolves stash their car keys.

Right, but I only started doing that a few days ago, and I didn't think ozok had been reinstalled in that time. debathena / livecd / ezyang 16:57 (Edward Z. Yang) Ozok was reinstalled on April 12th debathena / livecd / xavid 16:58 ('Do rocks chew their cud?') (Previously, the live CD would just be totally broken if there didn't exist a more recent kernel to upgrade to at build time.) debathena / livecd.d / jdreed 17:00 (This zephyr does not necessarily refle Is the LiveCD still a manual build process? Weren't we going to do something about that? debathena / livecd / xavid 17:00 ('Look! It's really happy! And by happy, I can replace the explicit one with a call to mkinitramfs, but getting the postinst to DTRT will be more difficult. debathena / livecd / andersk 17:00 (Anders Kaseorg) Well, how do the Ubuntu guys do it? debathena / livecd.d / xavid 17:01 ('Sucks-to-be-you-tastic.`) The Live CD is automated but still has to be run manually, mostly because we're not past the point where we need to manually test each new iso debathena / livecd / xavid 17:02 (“Can vampires suck blood from rocks?”) No idea? My main reference for this has been https://help.ubuntu.com/community/LiveCDCustomization, which doesn't mention this issue. debathena / livecd / andersk 17:05 (Anders Kaseorg) Hmm, is the official CD’s casper/initrd.gz different from the /boot/initrd.img-2.6.27-11-generic in the filesystem image? debathena / livecd / xavid 17:05 ("Never bite a gift horse in the neck.") I assume so. debathena / livecd / xavid 17:08 ('Sucks-to-be-you-tastic.`) (Based on this new information; before I'd assumed they were the same.) debathena / livecd / andersk 17:10 (Anders Kaseorg) Have you looked at https://help.ubuntu.com/community/LiveCDCustomizationFromScratch ? debathena / livecd / xavid 17:18 (“I like horse-molesting monkeys.”) Hmm; that's worth looking at. debathena / livecd / xavid 17:25 (“Where does the scary glowing man eat the Though, it looks like in those instructions it also uses the initramfs generated by installing a kernel, and has the same initrd in both the actual /boot and the outer /casper, so that doesn't address this. debathena / livecd / xavid 17:25 (“Welcome back cybergirls! and you—honorar What are the symptoms of compcache being enabled? Are you certain that normal Ubuntus installed from a Live CD don't have it enabled? debathena / livecd / ezyang 17:26 (Edward Z.

#282 | fixed | Java breaks new Live CD -workstation installs | xavid | xavid |
Description |
Java fails to install from the Live CD because it doesn't prompt the user for the license. This prevents debathena-workstation from actually successfully installing, and among other things makes aptitude decide it would be a great idea to remove twenty million things next time you try to do anything. I should figure out whatever PXE does to preseed license acceptance and do something similar. |

#283 | fixed | debathena-workstation Live CD install doesn't display feedback | xavid | xavid |
Description |
Since the debathena-workstation Live CD install installs -workstation in the success_command, it doesn't display feedback to the user and generally looks like the machine is frozen. We should figure out how to add it to the other install tasks so it actually reveals it's making progress, especially since it takes about three million years now. |
