Per the title, how do I make changes to the file /etc/gai.conf take effect in Ubuntu 20.04 without a reboot? (I altered /etc/gai.conf to force prioritization of 4to6 (IPv4 to IPv6) tunnel traffic over IPv4 traffic, but the change didn't take effect until after a reboot.)

`kill 1 prozesspid` sent a SIGHUP(Hangup) `kill -L` gives a little overview. – nobody May 06 '20 at 07:56
