Broken links under /dev/.udev/db ?

[Declan Mullen <declan@jadplace.com>]

Hi

Is it normal for there to be many broken symbolic links under the 
/dev/.udev/db directory ?

eg
class@vc@vcsa5 -> vcsa5
block@md2 -> md2
class@misc@device-mapper -> mapper/control
block@loop0 -> loop0
block@ram0 -> ram0

Should I be concerned that so many of the symbolic links are pointing to 
files that do not exist ?

I'm running etch with the latest updates. My uname output is:
Linux jack 2.6.18-5-vserver-k7 #1 SMP Mon Dec 24 19:45:10 UTC 2007 i686 
GNU/Linux

I'm unfamiliar with the /dev/.udev feature, so apologies if this is a 
dumb question.

Regards,
Declan
