[Pkg-samba-maint] Bug#652942: dhcp hook runs reload on shutdown (after service has been stopped)

[Michael Biebl]

Package: samba-common
Version: 2:3.6.1-3
Severity: important

Hi,

if you are using ifupdown and dhcp to manage your network device,
you'll get the following message on shutdown

INIT: Switching to runlevel: 0
INIT: Sending processes the TERM signal
Using makefile-style concurrent boot in runlevel 0.

See how the reload happens after samba has already been stopped.
This reload seems to be triggered by the dhcp enter hook.
