Инструкции по загрузке Koji
🔗 Скачать Koji
Сборки ядра можно загрузить с koji с помощью инструмента командной строки.
🔗 Рабочая станция Fedora
Установите Koji на рабочую станцию Fedora 39, если она еще не установлена:
$ sudo dnf install koji
🔗 Fedora Silverblue, Киноит, Sericea, Onyx, CoreOS, IoT
Установите Koji в набор инструментов:
Install Koji in a toolbox:
$ toolbox create
$ toolbox enter
$ sudo dnf install koji
Or directly on the host:
$ rpm-ostree install koji
and reboot
🔗 Список доступных сборок ядра
Вы можете просмотреть доступные сборки ядра с помощью:
$ koji list-builds --package=kernel --after="2024-01-21" --pattern "kernel-6.7*"
🔗 Скачать ядро
Загрузите RPM-пакеты для сборки ядра 6.7, которую вы хотите протестировать, в тестовый каталог, например kernel-6.7.1-200.fc39 :
$ mkdir -p ~/work/kernel_test
$ cd ~/work/kernel_test
$ koji download-build --arch=$(uname -m) kernel-6.7.1-200.fc39
🔗 Install kernel
🔗 Fedora Workstation
Update your kernel:
sudo dnf update kernel-*.rpm
and reboot.
Это не обязательно, установить kernel-6.7.1-200.fc39 можно и не затирая текущего. Если технический сленг не проблема смотри прямо
Я не делал перевод всего документа. Cмотри если надо этот фрагмент
🔗 Fedora Silverblue, Kinoite, Sericea, Onyx, CoreOS, IoT
If not done so already, download the kernel:
Download the RPMs for the 6.6 kernel build you want to test to a test directory, for example kernel-6.7.1-300.fc39:
$ mkdir -p ~/work/kernel_test
$ cd ~/work/kernel_test
$ koji download-build --arch=$(uname -m) kernel-6.7.1-300.fc39
Override the kernel:
$ rpm-ostree override replace kernel-modules-core-6*.rpm kernel-core-6*.rpm kernel-modules-6*.rpm kernel-6*.rpm kernel-modules-extra-6*.rpm
and reboot.
Ядро 6.7 будет стабилизировано на Fedora 39 в течение месяца ( из прошлого опыта ) без излишней суеты. Тест на KVM госте, как правило, дает стабильное ядро 6.7.2 спустя 3-4 недели и на bare metal . Virtual box или любой другой гипервизора 2-го типа использовать не стоит, если у Вас серьезные намерения ;)
