[Techtalk] updatedb hard drive thrashing

[Deanna Dunker]

I've noticed that sometimes it won't allow me to use the Find utility until 
I've ran updatedb.  I'll go to find a file, and a message will pop up 
saying something along the lines about how the search wont be completed 
until I've run updatedb as root.  This has happened to me several times in 
RH9, which I've been running for a few weeks now. I've never had that 
problem in RH8.

Is there a way around it?  I've just been trying to find files through the 
GUI (*cringes*, yes I'm a gui-gal).  Would I be able to search without 
having to wait to updatedb another way?  Also, would this affect Ed's 
searching capabilities if he uninstalled the program?
