Package: udev
Version: 167-2
Severity: normal
I add an
ls /dev
echo
sleep 5
ls /dev
at the very end of /etc/init.d/udev then reboot
On the boot screen, the first ls doesn't show my partitions
dev/sda1,/dev/sda2,etc, while the second does. Without that sleep, my
partitions aren't there by the time /etc/init.d/mountall.sh gets executed which
of course is a problem.
It would seem that the "udevadm settle" isn't doing what's expected?
