[systemd-devel] A problem with reboot and halt.

[Badiu Mircea Gabriel]

Hello,

I am using systemd 35 on x86 architecture, and I have a problem with the 
reboot and halt services, don't work very well, only after I type reboot 
twice or three times the system is rebooted. I think that is a process 
or something hang and it takes to long to restart, ot it can't umount 
all devices.

reboot.service
[Unit]
Description=Reboot
DefaultDependencies=no
Requires=shutdown.target umount.target final.target
After=shutdown.target umount.target final.target

[Service]
Type=oneshot
ExecStart=//bin/systemctl --force reboot

halt.service
[Unit]
Description=Halt
DefaultDependencies=no
Requires=shutdown.target umount.target final.target
After=shutdown.target umount.target final.target

[Service]
Type=oneshot
ExecStart=//bin/systemctl --force halt

The option reboot --force works but I need reboot and halt to work properly.

This is the output after typing three times reboot, only the third time 
system is rebooted :

Can anybody help me please?

P.S. systemctl restart reboot.service
        systemctl restart halt.service

are rebooting and halting the system but I need reboot and halt.

Thank you
