packages requiring me to reboot...

[Nathanael D. Noblet]

Hello,
   I feel like there are an increasing number of packages requiring a 
system reboot. I'm wondering why. The following updates were installed 
today, and required a full system reboot. I can't seem to find any 
package in the list that I can conceivably see requiring a reboot, is it 
that PK doesn't have the concept of X logout vs reboot? Is it a bug in 
the packaging or PK or is there anything I can do/file to improve the 
situation?

Wouldn't it be sufficient to logout? Is it a bug?
