Hi all,

I'm trying to figure out why my initqueue scripts are never called.
Eg 95fcoe is just installing an initqueue job, which should call
'fcoe-up' on the interface.
However, this script is never called, irrespective of any 'fcoe=3D'=20
parameters.

Looking a dracut-initqueue.sh, we have this:

while :; do

     check_finished && break

     udevadm settle --exit-if-exists=3D$hookdir/initqueue/work

     check_finished && break

     if [ -f $hookdir/initqueue/work ]; then
         rm -f -- "$hookdir/initqueue/work"
     fi

     for job in $hookdir/initqueue/*.sh; do
         [ -e "$job" ] || break
         job=3D$job . $job
         check_finished && break 2
     done

     udevadm settle --timeout=3D0 >/dev/null 2>&1 || continue
=2E..

and check_finished is:

check_finished() {
     local f
     for f in $hookdir/initqueue/finished/*.sh; do
         [ "$f" =3D "$hookdir/initqueue/finished/*.sh" ] && return 0
         { [ -e "$f" ] && ( . "$f" ) ; } || return 1
     done
     return 0
}

IE if no scripts are present in the 'finished' queue,=20
'check_finished' will return '0', causing the main initqueue to=20
short-circuit and the actual initqueue jobs will never be executed.

Is this the intended outcome?
IE are all jobs for the initqueue are _required_ to supply a=20
'finished' job?

I would have thought it to be a bit more permissive, ie do a
'return 1' if no finish j0bs have been found ...

Cheers,

Hannes
