Hi,
I am seeing an oddity in the CGroup output of systemctl status ran on
some units. On the other hand, systemd-cgls shows correct information.
Here is an example:
------
$ systemctl status netctl@wan.service
netctl@wan.service - DHCP connection on bond0
Loaded: loaded (/etc/systemd/system/netctl@wan.service; enabled)
Active: active (exited) since Mon 2014-08-11 11:51:05 EDT; 1h 20min ago
Docs: man:netctl.profile(5)
Process: 645 ExecStart=/usr/lib/network/network start %I (code=exited,
status=0/SUCCESS)
Main PID: 645 (code=exited, status=0/SUCCESS)
$ systemctl status netctl@wlan.service
netctl@wlan.service - Secure wireless uplink
Loaded: loaded (/etc/systemd/system/netctl@wlan.service; enabled)
Active: active (exited) since Mon 2014-08-11 11:50:58 EDT; 1h 16min ago
Docs: man:netctl.profile(5)
Process: 489 ExecStart=/usr/lib/network/network start %I (code=exited,
status=0/SUCCESS)
Main PID: 489 (code=exited, status=0/SUCCESS)
CGroup: /system.slice/system-netctl.slice/netctl@wlan.service
501 wpa_supplicant -B -P /run/wpa_supplicant_wlp3s0.pid -i wlp3s..
------
However,
------
$ systemd-cgls /system.slice/system-netctl.slice/netctl@wlan.service
/system.slice/system-netctl.slice/netctl@wlan.service:
501 wpa_supplicant -B -P /run/wpa_supplicant_wlp3s0.pid -i wlp3s0 -D ...
$ systemd-cgls /system.slice/system-netctl.slice/netctl@wan.service
/system.slice/system-netctl.slice/netctl@wan.service:
663 dhcpcd -4 -q -t 30 -L bond0
------
So, both units are actually instances of the same netctl@.service. This service
calls a script (/usr/lib/network/network) which in turn starts wpa_supplicant
or dhcpcd. The difference between the two cases is that dhcpcd forks yet
another process:
------
$ journalctl -u netctl@wan.service | grep forked
Aug 11 11:51:05 borei dhcpcd[650]: forked to background, child pid 663
------
This is systemd-215 running on ArchLinux. Any ideas why this is happening?
Thanks,
