Package: ifupdown Version: 0.8.13 Severity: normal
This is related to Bug#761909 (NFS not brought down during shutdown or reboot due to the network dying too soon), which I'm still seeing on my machine with ifupdown 0.8.13 and systemd 231-6, at least with wireless connections (I haven't checked wired connections recently). I looked at the dependencies of my NFS share mount; systemctl list-dependencies oneforall.mount gives: oneforall.mount ● ├─-.mount ● ├─system.slice ● └─network-online.target ● └─networking.service so in theory it should be working correctly. _However_, there is nothing in there preventing dbus from being killed before the network is brought down, and if dbus gets stopped too early then wpa_supplicant will die too, and my wireless connection will die due to wpa_supplicant dying, which forcefully brings down the whole network even with systemd thinking it's still active. The solution in this case is to add a dependency of networking.service on wpa_supplicant.service (which in turns depends on dbus and therefore prevents dbus from being brought down too early). Ideally this dependency should only be added when a network connection that needs WPA is brought up (and removed when no network connections depending on WPA are up). I have verified that this works at least on my system: testing by forcing a runtime dependency of this sort manually seems to fix the NFS share unmounting, as well as other network-related shutdown/reboot issues I come across from time to time. -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.7.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages ifupdown depends on: ii adduser 3.115 ii init-system-helpers 1.44 ii iproute2 4.6.0-4 ii libc6 2.24-2 ii lsb-base 9.20160629 Versions of packages ifupdown recommends: ii isc-dhcp-client [dhcp-client] 4.3.5~b1-1 Versions of packages ifupdown suggests: ii ppp 2.4.7-1+3 pn rdnssd <none> -- no debconf information
