| melodie | hi | 11:13 |
| sladen | hello melodie | 11:14 |
| melodie | hi sladen | 11:14 |
| sladen | just ask your question so that everyone can see it at the same time | 11:14 |
| melodie | I have a question about the content of ISO, because I want to improve Bento Openbox Remix build. The question is about pool/dist and about EFI or any added package such as drivers for specific hardware, and so on: how does the system know if it has to choose a package in the pool directory? Does it work just by "magic hardware detection" and some pipes between it and apt? | 11:16 |
| melodie | I hope my question does not sound too dumb, as I really don't have a clear idea about that sphere of processes | 11:16 |
| melodie | sladen do you think anyone here will have a doc to point me to, or insights they can provide? | 11:19 |
| sladen | asking questions is never dumb | 11:19 |
| melodie | thanks :D | 11:19 |
| sladen | however I'm still trying to work out if /I/ understand the question correctly, in order to be able to answer it or point you towards somebody who might know | 11:19 |
| sladen | melodie: have you got an example of package that might/might not be chosen, and which you have in mind? | 11:20 |
| sladen | melodie: eg. are you thinking of something like an Nvidia graphics driver, or a USB modem driver? | 11:21 |
| sladen | melodie: ideally all hardware should do something useful/sensible when plugged in, and it's a bug if it doesn't | 11:21 |
| melodie | yes, first idea is about efibootmgr | 11:21 |
| sladen | melodie: but remixes are normally more about remixing the user applications/desktop environments/languages rather than hardware support | 11:22 |
| melodie | I aim to bring Bento Openbox Remix to a tech level as close as possible to what is provided by the official versions | 11:22 |
| melodie | I do it starting from "outside", and will dive into the tech deeper and deeper as time goes | 11:23 |
| melodie | 2012: the remix is LTS and works (done with Ubuntu Builder) | 11:23 |
| melodie | 2014 started working on the Trusty LTS (still the same tool but is not dev anymore, and someone shows me the seeds, however my configs aren't packaged so I have to be patient) | 11:24 |
| sladen | I think vaillant used to be one of the developers of Ubuntu Builder | 11:24 |
| melodie | now I start using Customizer instead of Ubuntu-Builder, but I want to master the "pool/dist" area, which I haven't so far. next I'll see if I can learn packaging the user prefs | 11:24 |
| sergiusens | cjwatson, hey, is that "y-series" for destination series I see on launchpad's copy packages interface expected? | 11:25 |
| melodie | never mind Ubuntu Builder, it's over. Customizer works and while the project continues to provide recent ISO's it's alive. Between versions I want to learn to make it better | 11:25 |
| cjwatson | sergiusens: yes, you won't actually be able to copy to it because it's marked Future but the series exists | 11:26 |
| cjwatson | sergiusens: though maybe the copy target vocabulary should filter it out, file a bug | 11:26 |
| melodie | sladen when I'll handle pool/dist and be able to package the parts that still need to be packaged, I'll do a meta-package, a session and see if I can start using real seeds. | 11:27 |
| sergiusens | cjwatson, sure thing, thanks | 11:27 |
| melodie | sladen so in the case of efibootmgr package, and knowing there is also the BOOT/EFI/ directory in the 64bits isos, how does that work under the hood? would you know that, | 11:28 |
| melodie | ? | 11:28 |
| sladen | FourDollars: ^^think you might have been the last person to touch efibootmgr (since then it's been a straight import from Debian) | 11:29 |
| FourDollars | sladen: yes? | 11:30 |
| melodie | sladen oh! | 11:30 |
| melodie | hi FourDollars | 11:30 |
| FourDollars | Hi melodie | 11:30 |
| melodie | this is about my noobs questions related to how pool/dist and other additions such as BOOT/EFI/* are "seen" and used in the 64bits ISOs (or other pool packages seen but the hardware recognition tools) | 11:31 |
| melodie | I'd like to understand how all this is processed during the start of the live and or after it's started | 11:31 |
| sladen | melodie: I don't know boot stuff well anymore; but I should imagine that locating packages comes a lot later than the early stages of boot. So they seem to be going in different directions | 11:34 |
| FourDollars | The files under BOOT/EFI/* can be downloaded from some url. Let me search for it. | 11:34 |
| sladen | melodie: EFI->Grub->Kernel->initramfs->rootfs->...->Debian-installer (or any particular GUI font end for it) | 11:35 |
| melodie | sladen where "EFI →" is the EFI in the "BIOS / EFI" computer? | 11:36 |
| melodie | that would be "EFI → Grub-EFI" ? | 11:36 |
| FourDollars | /EFI/BOOT/BOOTx64.efi is defined by the UEFI spec. for 64 bits UEFI BIOS. | 11:36 |
| melodie | FourDollars I read you | 11:37 |
| FourDollars | Read it from http://www.uefi.org/specifications | 11:37 |
| FourDollars | /EFI/BOOT/BOOTx64.efi will bring up the GRUB and then GRUB will bring up the Linux kernel and initramfs. | 11:38 |
| melodie | how does the "system" (what part of it?) acknowledges the /EFI/BOOT/BOOTx64.EFI|grubx64.efi presence? | 11:40 |
| melodie | FourDollars I try to understand how the "magic" works there | 11:40 |
| FourDollars | That is what UEFI BIOS does. | 11:40 |
| sladen | melodie: the EFI firmware looks through the available boot devices, and looks if any of the available boot devices contains a file called '/EFI/BOOT/BOOTx64.EFI', loads it into memory, and runs it | 11:41 |
| FourDollars | melodie: UEFI BIOS will try all boot entries in NVRAM and then search for some pre-defined files. | 11:41 |
| FourDollars | melodie: There is no magic and they are documented at http://www.uefi.org/specifications. | 11:42 |
| melodie | sladen oh ok! | 11:42 |
| melodie | FourDollars ok, some reading to do, thanks | 11:43 |
| FourDollars | melodie: no problem | 11:43 |
| melodie | if you have insights for me, about how that works for other packages in pool in the ISOS? I have browsed through the pool of several Ubuntu official flavors and noticed they don't necessarily contain the same packages, which means the devs did different choices (not fixed by an Ubuntu convention for instance) | 11:45 |
| FourDollars | melodie: BTW, the efibootmgr only edits some variables in NVRAM as I know. | 11:45 |
| melodie | FourDollars I don't know about that, it's deeped (lower/closer to the hardwareà that I have learned about. | 11:46 |
| melodie | FourDollars I just browsed my favorite computer dictionnary to read about NVRAM : that's the firmware, right? | 11:47 |
| melodie | deeped/deeper* (sorry for the typo) | 11:47 |
| sladen | melodie: one (shouldn't) need to worry about EFI when remixing | 11:47 |
| FourDollars | melodie: http://archive.ubuntu.com/ubuntu/dists/trusty/main/installer-amd64/current/images/cdrom/debian-cd_info.tar.gz | 11:48 |
| melodie | sladen I use Ubuntu Mini Remix to build on it, which means there is no EFI nor pool/dist at the beginning | 11:48 |
| melodie | FourDollars I look | 11:48 |
| TJ- | melodie: UEFI boot from removable media expects to find the Simple Media Boot Path, which means an EFI System Partition with the boot-loader at /EFI/BOOT/BOOT${ARCH}.EFI | 11:48 |
| melodie | FourDollars that's the sources? | 11:49 |
| sladen | melodie: Grub | 11:50 |
| FourDollars | melodie: The files under /EFI/BOOT/ such as BOOTx64.efi is in ./grub/efi.img in http://archive.ubuntu.com/ubuntu/dists/trusty/main/installer-amd64/current/images/cdrom/debian-cd_info.tar.gz. | 11:50 |
| melodie | TJ- yes, ok I get this. (I have installed only on two machines having UEFI so far, and learned that side of the story) | 11:50 |
| FourDollars | s/is/are/ | 11:50 |
| TJ- | melodie: OK, I only just came in. Was there some other aspect to the info you are looking for? | 11:51 |
| melodie | TJ yes, about the packages in pool/dist : what process makes them either chosen or ignored, depending on the hardware where the live boots? | 11:51 |
| sladen | melodie: are you wondering about different architectures (x86 vs amd64) | 11:52 |
| melodie | FourDollars I would not know yet how to use the link you just gave me, apart from looking what it contains (but I'll learn that later when the time comes, now I just try to understand the mechanics) | 11:52 |
| TJ- | melodie: Do you mean, for an ISO image which has package A in its /pool/ already, what makes the installer (d-i/ubiquity) install that package, or do you mean what controls the packages actually included in the /pool/ at CD image creation time? | 11:52 |
| melodie | sladen no, I guess 32bits don't have UEFI? | 11:53 |
| FourDollars | melodie: OK | 11:53 |
| TJ- | melodie: there is 32-bit UEFI too | 11:53 |
| melodie | TJ- " what makes the installer (d-i/ubiquity) install that package" and if you explain me what controls the package installed in the pool at CD image creation time, I'll just ask you if the info in that doc is enough for me to get the anwser? → | 11:54 |
| melodie | https://help.ubuntu.com/community/InstallCDCustomization#Modify_pool_structure_to_include_more_packages | 11:55 |
| melodie | TJ- ah! | 11:55 |
| TJ- | melodie: The installed image, including packages, is generally controlled by a preseed file | 11:55 |
| melodie | 32 bit uefi... | 11:55 |
| TJ- | melodie: the preseed file is generally included on the kernel command-line at boot-time, by the boot-manager | 11:56 |
| melodie | TJ- ok preseed, the last thing I'll need to worry about, once I will have created packages for everything, which I haven't yet | 11:56 |
| melodie | I'll do some tests with the command lines included in that part https://help.ubuntu.com/community/InstallCDCustomization#Modify_pool_structure_to_include_more_packages | 11:59 |

| melodie | FourDollars yes! | 12:01 |

| FourDollars | s/extract/decompress/ | 12:01 |
| melodie | some time I'll ask to be explained the different contents in /usr/share/casper, for now all I know is that some scripts are to be considered and or added in the casper/bottom section. | 12:01 |
| melodie | FourDollars initrd.lz needs to be renamed to be extracted, right? | 12:02 |
| melodie | to .gz then gunzip? | 12:02 |
| TJ- | melodie: best thing is to read the source/documentation od the cdimage package. See e.g. http://bazaar.launchpad.net/~ubuntu-cdimage/ubuntu-cdimage/mainline/view/head:/README | 12:02 |

| infinity | ogra_: xenial's the devel series, not sure what you expect. | 18:25 |
| infinity | ogra_: A wily build would need DIST=wily | 18:25 |
| ogra_ | infinity, dunno, that image builds only default to it once it actualy can build ... i.e. once the archive is complete enough :) | 18:26 |
| infinity | The arvhive is "complete" from day 1... | 18:27 |
| infinity | archive, too. | 18:27 |
| infinity | It's not like we start from scratch. | 18:27 |
| ogra_ | well, i have different 404s on the different arches in the logs | 18:27 |
| infinity | Log? | 18:27 |
| ogra_ | oh and we use a PPA | 18:28 |
| ogra_ | which also doesnt have xenial support yet | 18:28 |
| infinity | Right, if your PPA is 404ing, you could mass copy from wily to xenial. :P | 18:28 |
| ogra_ | well, i could just turn on xenial at all for the PPA, prehaps thats sufficient ... | 18:29 |
| cjwatson | ogra_: yeah this is just your PPA | 18:32 |
| ogra_ | right | 18:32 |
| cjwatson | ogra_: you can only "turn it on" by uploading or copying something into it | 18:32 |
| ogra_ | i just did a xenial upload to it, that should get me the Packages files | 18:32 |
| cjwatson | mass copying would normally be sensible, why not do that? | 18:33 |
| ogra_ | the wily stuff should all be in archive already anyway | 18:33 |
| cjwatson | ok, well, either make the Packages files exist, or make your lb config stop using the PPA, one or the other | 18:33 |
| * ogra_ would like to only use the PPA for overrides and in case something is missing, directly copy to the archive | 18:34 | |
| ogra_ | a new release is a good reason to clean up :) | 18:34 |
| dobey | or make it not fail if the Packages file in the PPA doesn't exist :) | 18:45 |
| dobey | robustness ftw | 18:45 |

| === pstolowski|afk is now known as pstolowski | ||
| infinity | dobey: I wouldn't call that robust, I'd call it just the opposite. If you ask it to use a PPA and the PPA is busted, that *should* fail. | 19:04 |

| sil2100 | cyphermox, doko: re: the ocaml transition, looking at xstrp4 it seems that the installability issue would be resolved by us pullin in the camlp4 source package from Debian - which, on the other hand, requires us to first merge the new ocaml version from Debian | 21:03 |
| sil2100 | cyphermox, doko: so I guess this would have to wait as doko mentioned Debian prepares a new ocaml version anyway or something | 21:04 |
| sil2100 | Moving forward | 21:05 |
| sil2100 | cyphermox, doko: anyway, how would you guys prefer me to resolve those issues? Since for most cases I don't have the permissions to merge/sync - is poking here ok? | 21:13 |
