[ILUG] LVM symlinks not created during startup

[Jean Francois Bucas]

Hi Steph,

thanks for your answer.

It turns out that udev-initramdisk doesn't handle all the events and
some of the remaining events are dropped before being transmitted to the
udev-rootfs.

The proposed patch seems to work for me.

Many thanks,
Jef
