I was wondering why my gentoo box was no longer forwarding my IPv4 & IPv6 packets. I tracked it down to the sysctl.conf values not being loaded, and this happened only after I upgraded to sys-apps/openrc-0.13. rc-update shows that sysctl is loaded at boot time: # rc-update ... swap | boot swapfiles | boot sysctl | boot sysfs | sysinit syslog-ng | default ... However, when after the boot process, I enter this into a shell: # sysctl -p net.core.rmem_max = 6291456 net.core.wmem_max = 4194304 net.ipv4.ip_forward = 1 net.ipv6.conf.all.forwarding = 1 net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.all.rp_filter = 1 net.ipv4.tcp_syncookies = 1 Those are all the setting changes I made in sysctl.conf and it shows that they were not loaded during boot time. Reproducible: Always
