Bug#444980: udev not restarted after exiting runlevel 1

[Dmitry Bogatov]

Seems old discussion did not ended in solution. Let us try again.

Dear udev maintainers, did anything changed? Are there still problems
running /etc/init.d/udev from runlevel 1 (when udev daemon was killed)
manually by sysadmin to restart it?
