From b2cfacf1180e4b3fcbb2ae2ea52cf270ef74e971 Mon Sep 17 00:00:00 2001 From: Julian Andres Klode Date: Sun, 7 Aug 2016 00:45:25 +0200 Subject: Handle interrupt when running Pre-Install hooks If we receive an interrupt, set a flag and do not abort immediately without waiting for the child. Once the child exited, exit with an error if the interrupted flag is set.
