What is your kernel command line?
BOOT_IMAGE=/boot/vmlinuz-3.12.18-4-default \
root=UUID=7b90aa11-62ba-4260-81c6-bcf43914e97e \

do a rd.break=initqueue and look in the
/lib/dracut/hooks/initqueue/finished
directory.
If you use systemd in the initramfs, you should have:
/usr/lib/systemd/system-generators/dracut-rootfs-generator
in the initramfs, which transforms root=UUID=... into the finished hook.
You should be able to test it in the dracut shell with:
# bash -x /usr/lib/systemd/system-generators/dracut-rootfs-generator
Which seems to be the problem; the generator is present, but apparently not
called.
Once I execute the above line the 'finished' entry for the root fs is there.
From which I surmise that the generator hasn't been called.
Hmm.
Does it have the executable bits set?
Argl. Totally stupid.
Look at modules.d/99base/module_setup.sh:
## save host_devs which we need bring up
if [[ $hostonly_cmdline == "yes" ]]; then
if [[ -f "$initdir/lib/dracut/need-initqueue" ]] || !
dracut_module_included "systemd"; then
(
if dracut_module_included "systemd"; then
DRACUT_SYSTEMD=1
fi
PREFIX="$initdir"
. "$moddir/dracut-lib.sh"
for _dev in ${host_devs[@]}; do
[[ "$_dev" == "$root_dev" ]] && continue
_pdev=$(get_persistent_dev $_dev)
case "$_pdev" in
/dev/?*) wait_for_dev $_pdev;;
*) ;;
esac
done
)
fi
fi
So if /etc/fstab contains just the root device (or if the swap
device resides on a different device which is initialized earlier)
the initqueue will _never_ run, and the worker scripts will never
be executed.
Once I remove the '[[ "$_dev" == "$root_dev" ]] && continue'
line the system boots.
Cheers,
Hannes
