Package: ifupdown
Version: 0.7.53.1
Severity: normal
Dear Maintainer,
When ifup spawns a new process like wpa_supplicant (e.g. when
using the config pasted below), then the spawned wpa_supplicant
is created in the current cgroup. This is problematic if
ifup/ifdown is executed from another service (e.g. a
configuration management tool) as stopping the service then also
causes wpa_supplicant to stop (systemctl stop terminates all
processes in the same cgroup), possibly disrupting the network
connection.
Regards
Simon
