net.ipv4.ping_group_range 활성화

Fedora 31 now supports the net.ipv4.ping_group_range kernel parameter for all user groups. This change enables all users to create Internet Control Message Protocol (ICMP) Echo sockets without using the setuid binaries, or having the CAP_NET_ADMIN and CAP_NET_RAW file capabilities.

As a result, the rootless podman containers are now able to use the ping utility. This change applies also to users developing on the Fedora Silverblue variant, who use containers created through the toolbox utility.

i686 커널을 위해 부팅 가능한 이미지가 없습니다

페도라 31은 더 이상 i686 시스템을 위한 32-비트 커널 또는 부트 이미지를 제공하지 않습니다. 이와 같은 변경은 32-비트 하드웨어를 갖고 있는 사용자의 점점 감소량에 따른 결과입니다.

kernel-headers 꾸러미는 i686 꾸러미에서 계속 존재합니다.

페도라는 이제 기본적으로 cgroups-v2를 사용합니다

Enablement of control groups version 2 (cgroups-v2) by default allows the system utilities to conveniently take advantage of new functionality and fixes this kernel feature brings.

Users have to update any tools or scripts they used for manual configuration of cgroups-v1 so that they reflect cgroups-v2 now. The tools or scripts should not require any changes, if they utilized the systemd interfaces.

Some container engines leak the control group hierarchy into containers. This could pose a problem for container images that expect to be running in a control group version 1 environment. This change is tied to the removal of the docker package in Fedora 31; see the Containers section for details.
