| yogg | Hi | 14:36 |
|---|---|---|
| yogg | I playing around with automated installation of an ubuntu-server (24.04) via a "user-data" file which is stored on the install CD. I have a list of packages which should be installed listed in the "packages:" section. | 14:36 |
| yogg | In the installer itself every package will be installed by starting a chroot, install one package and close the chroot. This loops over the complete list and takes forever because there is so much overhead. Is there a way to install all the packages in one bulk command? | 14:36 |
| znf | Does anyone know what scripts does ubuntu run when installing a new kernel version that triggers the changing of the /boot/vmlinuz + initrd.img symlinks? | 14:36 |
| znf | I've installed an older kernel than my current running one, and it set up the symlinks (and I'm guessing other defaults) for the older version, which is not something I want | 14:37 |
| znf | and the only info I can find online is about how to make grub boot it by editing the configs, which is not something I want to do right now | 14:38 |
| yogg | znf: i think "/etc/kernel/postinst.d/xx-update-initrd-links" | 14:38 |
| znf | mkay, that worked | 14:42 |
| znf | thanks | 14:43 |
| blackboxsw | yogg: this is related to subiquity and I can see what you are saying w.r.t. one operation per package in list in the ephemeral boot environment due to it's interaction w/ curtin to install in the chroot here https://github.com/canonical/subiquity/blob/main/subiquity/server/controllers/install.py#L689-L725. Not certain offhand if there is a way to batch those pkgs download through the Ubuntu installer(subiquity) packages: | 15:29 |
| blackboxsw | yogg: but I know the ubuntu installer allows for passing user-data to cloud-init on "first boot" after the installer exits by passing "autoinstall:\n user-data:\n packages: [pkg1, pkg2]" that would allow cloud-init on first boot to batch the installed packages during that first boot (if those packages don't contain required config/services that are required on first boot | 15:31 |
| blackboxsw | *correction: if those packages don't deliver systemd services that are needed early in first boot of the installed system. | 15:33 |
| yogg | blackboxsw: thx, I do now a "late-command" and install most of the packages there. Not super pretty works ^^ | 15:42 |
| blackboxsw | yeah, that's an option too. I'd await a subiquity person (I'm cloud-init; like falco-jr) for alternative suggestions if there are some | 15:43 |
| yogg | One thing that I could not find out yet. Ubuntu "autoinstall" uses nearly the same config as cloud-init as I see and everywhere it is called cloud-init. But it is not cloud-init? Its only similar? | 15:51 |
| cpete | yogg: Indeed. Autoinstall is just another yaml config, which is often delivered by cloud-config, but they are distint. | 16:14 |
