Package: ucarp
Version: 1.5-2
Severity: normal
Tags: patch
ucarp is still a session leader after the daemonize function. Also when an
instance
receives a HUP - signal it just exits without calling a shutdown script, which
could
lead to a interface being up on both master + slave (at least for testing
purposes).
