Oh my, there is an awful lot of input. I will have to run this again and 
capture it to a text file. Huh, chrome sandbox had suid? How come? Let me 
run this more and find out how bad this is.

I don't really know how to tell what should and should not have suid. I 
know that no browser sandbox should have it, and all the /bin /sbin/ and 
some others are alright, but there is a LOT of output from directories and 
even hard drives that should not have suid. I have backups of previous 
installations on other drives and they have suid too. /var/cache/.. has 
suid. This is bad. Do you think I can upload this for examination or might 
that not be prudent, unruh?

Thank you unruh.
