2022年5月：以下はCentOS 8からCentOS Stream 8への移行に役立ちました。
# sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*
# sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
# dnf install centos-release-stream -y --allowerasing
# dnf swap centos-{linux,stream}-repos
# dnf distro-sync --best --allowerasing
# reboot
