Subject: Don't ignore SIGCHLD, system() needs it.
X-Git-Tag: release-1.1pre1~13
X-Git-Url: https://www.tinc-vpn.org/git/browse?a=commitdiff_plain;ds=sidebyside;h=8b3cc695b56d4ab5e51c7e194153894f920b307f;p=tinc

Don't ignore SIGCHLD, system() needs it.

But we do ignore SIGPIPE, and tinc 1.0.x signals that are no longer used
(SIGUSR1 and SIGUSR2), since the default handler of these signals is to
terminate tincd immediately.
