[systemd-devel] how to depend the service which is triggerred by uevent

[lchina77]

Hi, All,
     I have two services:  service_A and service_B.  The service_A which depends on the tap0 uevent will configure the virtual net,  
while the service_B which depends on the virtual net should run After the service_A,  but  the "After=Service_A" seems to have no effect.


udev rule:
ACTION=="add", SUBSYSTEM=="net", DEVPATH=="/devices/virtual/net/tap0", TAG+="systemd", ENV{SYSTEMD_WANTS}+="service_A.service"


service_A.service:
[Unit]
Description=setting up bridge

[Service]
Type=oneshot
ExecStart=-/usr/bin/net_config.sh
RemainAfterExit=yes


service_B.service:
[Unit]
DefaultDependencies=no
After=service_A.service
After=local-fs.target


[Service]
Type=simple
ExecStart=/usr/bin/prog_B
Restart=always
OOMScoreAdjust=-941


[Install]
WantedBy=sysinit.target 


Could anyone give me some suggestion?
 Thanks!




Best Regards,
Li Cheng
