[systemd-devel] reliable way to check if udev is ready to serve requests

[Michael Biebl]

Hi,

is there a reliable way to check from a shell script that udevd is
running and able to serve request?
Say you want to run "udevadm trigger" but only if udevd is actually
able to process that request.

There is a udev_ctrl_send_ping() function, which looks like it could
be perhaps used for those. Unfortunately this is not exposed via
"udevadm control"

Regards,
Michael
