pppd completely ignores any signal when it runs 'nondetached' and is executing scripts like 'init' or 'connect' script. it only can be killed by "kill -9". responsible for this behavior is a patch which is should be a fix for the already resolved bug #181145 ( http://bugs.gentoo.org/show_bug.cgi?id=181145 ) , but which isn't a bug ! this bug doesn't appear with the original sources from "http://ppp.samba.org" but is introduced with the "kill-pg.patch". the bug described in #181145 isn't bug, since this behavior of pppd is well documented in the man-page. the problems this behavior may involve can be easily solved without touching "pppd", as i described in comments on #181145 ( http://bugs.gentoo.org/show_bug.cgi?id=181145#c2 ). but the patch introduced with #181145 causes new problems as i mentioned before.
Fixed in -r15.
