This is wrong. We really want to be able to check the configuration for correctness at startup. If you switch to using freebind by default, you loose that sanity check. And using freebind for all systemd users is basically the same as making it the default. Doesn't network-online.target do what you need? If no, why not? I am not against the freebind feature as such, it's useful for failover solutions/VRRP/etc. But I am strictly against advertising this as a workaround for broken systemd design. > > The patch needs latest APR-trunk currently, but it could be > rewritten to set IP_FREEBIND directly instead of using APR API (We > use that way for REUSEADDR socket option). > > Do you think FreeListen is good name for this feature, or would you > name/implement it differently? > > [1] https://www.freedesktop.org/wiki/Software/systemd/NetworkTarget/
