[systemd-devel] Q: When will WorkingDirectory be checked?

2021-12-16 Thread Ulrich Windl
Hi!

I have a simple question: When will WorkingDirectory be checked? Specifically: 
Will it be checked before ExecStartPre? I could not get it form the manual page.

Regards,
Ulrich Windl





[systemd-devel] varlink external client

2021-12-16 Thread Vishwanath Chandapur
Hi,

We have developed a varlink client as part of systemd source code,But we
would like to have the same client outside of systemd source code.

For that I guess we need to make below necessary changes like sd_*
interface.

varlink.c from src/shared to src/libsystemd
varlink.h from src/shared to src/systemd/

Please correct me if i am wrong

Thanks
Vishwa


[systemd-devel] How to disable user@UID.service when starting gdm user

2021-12-16 Thread 赵成义
Hi guys,


When systemd starts gdm user, user@UID.service is executed, and all services 
are started in the folder /lib/system/user.
In fact, gdm user doesn't need these services, so I think systemd doesn't need 
to start user@UID.service for gdm user.


Would you please tell me how I disable user@UID.service when starting gdm? 
thanks a lot.


$ ps aux | grep systemd
gdm 914 0.0 0.7 22152 14256 
?Ss 19:28 0:00 
/usr/lib/systemd/systemd --user


Best Regards,
Chengyi

Consider updating your systemd version to a newer version (or ask your
distro to backport the relevant patches). The predictable network
interface naming received a number of tweaks since 245, and it's
pretty likely this has since been fixed. Specifically, the
NAMING_SLOT_FUNCTION_ID feature flag introduced with v249 will likely
fix your case.

Thanks. What does 'udevadm info /sys/class/net/*' say?

Can you provide the output from 'udevadm test-builtin net_id 
/sys/class/net/'
for each of the four interfaces?
