Andrei,

I've found that running udevadm test /sys/block/sda/sda4 will create the correct link \
after having initialized a filesystem on /dev/sda4 with a label using mkfs -t xfs -L \
root -q -f /dev/sda4

Tried udevadm control -S

WORKED!

And found my bug!. I did stop the exec queue to prevent old md device to appear, then \
only restarted it if I create lvm (forgot to restat itin normal conditions)....

Thanks for your help and tips. (udev was running, but it was stopped...)

Olivier.

    Is udevd running? Do you have any other link for other devices? Do you
    have udev rules in initrd?
