Message-ID: <4A4C87DF.10904@redhat.com> (raw)

To move all "big" jobs out of the udev event handling, I introduce the 
"initqueue". This prevents the job from being killed by udev timeouts.

See
http://dracut.git.sourceforge.net/git/gitweb.cgi?p=dracut;a=commit;h=eab677a2164bccb3990487dc5ef4549b30cb1055

for the patch.

Basically inside a udev event, you don't do

RUN+="/sbin/ifup $env{INTERFACE}"

you now queue this in the initqueue with:

RUN+="/sbin/initqueue /sbin/ifup $env{INTERFACE}"

Inside init all jobs are worked on in serial order by the do_initqueue() function.

Now we have no more side effects due to the parallel nature of udev and still be 
fast, in case udev supports "udevadm settle --exit-if-exists="
