s6-linux-init v1.2.0.0 fixes an issue with systemd socket activation

[eriksjolund]

s6-linux-init version v1.2.0.0 has a new command-line option -W readyfd that was added in the git commit skarnet/s6-linux-init@8164ce1

If I understand correctly, this can be helpful when using socket activation of containers.

It seems earlier releases of s6-linux-init did not support systemd socket activation at all. For details, see github comment NginxProxyManager/nginx-proxy-manager#3922 (comment)

Side note: the latest release of s6-overlay (version v3.2.1.0) uses s6-linux-init v1.1.3.0.

I haven't used s6-linux-init, but I guess this news could be interesting for people who are using s6-linux-init with podman.
