interesting approach. |
This is because RHEL10 or other distributions which use zstd compression inside of systemd, the symbols could be collided and we need to unify the using zstd symbols. This is just for changing the way to linking libzstd libraries. No need to change for building rules in packaging. Signed-off-by: Hiroshi Hatake <hiroshi@chronosphere.io>
