According to https://access.redhat.com/solutions/444773 With Red Hat Enterprise Linux 7 and 8, the stablelist is valid for the particular major release. This means that once a symbol has been introduced into kABI for a particular major release, it will not be removed, nor will its meaning be changed during that kernel major release complete life cycle. With Red Hat Enterprise Linux 9, each minor release will have a unique stablelist that is valid throughout the minor release lifecycle. For more information on this, please refer to the following knowledgebase article; We are pinning the minor release for the duration of the build. So the stablelist for the minor version will be installed
1. Move DisableNouveau, InstallAdditionalKernelPackages from `update_and_reboot.yaml` to `parallelcluster.yaml`. This improves consistency of build between with and without `UpdateOsPackages` 2. Remove InstallEfiBootManager because the bug it was trying to work around already got resolved. 3. Move RHEL minor version pinning from `InstallPrerequisite` to the beginning of `PinVersion` for the following reasons 3.1 Even if we make mistakes pinning packages without installing, with minor version pinned, we will pin to the latest within the minor 3.2 `yum install -y yum-plugin-versionlock` will install the version within the minor 3.3 In terms of code style, RHEL minor version pinning fits in `PinVersion` better than `InstallPrerequisite` 4. For RHEL/Rocky, install kernel-headers, kernel-devel, kernel-devel-matched(RHEL/Rocky >=9) before pinning the version. For Ubuntu, install `linux-headers` before pinning the version 5. Add a Reboot after installing and pinning kernel packages
This commit improves the Rocky9 vault repository usage. Instead of using `wget` from the URL of the vault, this commit enables vault repository, so all subsequent `yum` commands will be able to use the vault. This reduces code duplication and improves robustness. Example of repo configuration in Rocky: ``` cat /etc/yum.repos.d/Rocky-AppStream.repo # Rocky-AppStream.repo # # The mirrorlist system uses the connecting IP address of the client and the # update status of each mirror to pick current mirrors that are geographically # close to the client. You should use this for Rocky updates unless you are # manually picking other mirrors. # # If the mirrorlist does not work for you, you can try the commented out # baseurl line instead. [appstream] name=Rocky Linux $releasever - AppStream mirrorlist=https://mirrors.rockylinux.org/mirrorlist?arch=$basearch&repo=AppStream-$releasever #baseurl=http://dl.rockylinux.org/$contentdir/$releasever/AppStream/$basearch/os/ gpgcheck=1 enabled=1 countme=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rockyofficial ```
