udev startup load time doesnt appear anymore

I installed some packages (splashy etc) wich created a lot of pacsave files and messed up my system pretty much. But nothing couldnt handle.
Exept this: udev doesnt show the overal loading time anymore it skips to the next operation.
I checked /etc/start_udev script and I saw in the bottom

echo "udev startup is finished! - time = $(( `date +%s` - $starttime ))"
exit 0

which I think is the code for the loading time to show up but it is not executed somehow.
Can somethink like that can be fixed?
my /etc/start_udev script

#! /bin/sh
#
# start_udev
# script to initialize /dev by using udev.

Exept this: udev doesnt show the overal loading time anymore it skips to the next operation.

i think this is done by rc.sysinit which belongs to the initscript package. i do not use splashy but i can see it depends on initscripts-splash so that could be the reason.

Re: udev startup load time doesnt appear anymore

Thanks a lot,
I uninstalled splashy and its initscripts-splash .
Reinstalled initscript and the loading time is back!
Maybe initscript-splash doesnt have a counter for that.
