[systemd-devel] Systemd daemon access permissions

[Zamar Ac]

Hello guys,

Upon system boot I'm not gettings active network. The log says:

"systemd-networkd[246]: Could not connect to bus: Permission denied"

I'm trying to log more details, but again hitting the same issue despite  
logged in as root upon boot. Why root access is denied to the bus?

"# SYSTEMD_LOG_LEVEL=debug /lib/systemd/systemd-networkd
name_to_handle_at on /dev: Permission denied
the udev service seems not to be active, disable the monitor
Could not connect to bus: Permission denied"

OK, as a workaround I manually modified   
/usr/lib/systemd/system/systemd-networkd.service instead, adding:

"[Service]
...
Environment=SYSTEMD_LOG_LEVEL=debug"

but apparently don't see more details about the problem in system log  
after reboot. Why? Generally, with what permissions systemd daemons like  
networkd run at boot? Do they have root permissions? If not, can I assign  
them root permissions, and how?

Another approach - looking for workarounds. Lets entirely bypass this  
systemd process until fixed in the future, since I need a working system  
right now. What config settings would allow to auto enable network after  
boot without networkd daemon running?
