What's the difference between updatedb and /etc/cron.daily/find?

["Chris Purves" <chris.purves@gmail.com>]

I am seeing different results from /etc/cron.daily/find and running
updatedb from the command line:

aims-07:~# /etc/cron.daily/find
aims-07:~# locate Access.pm
aims-07:~# updatedb
aims-07:~# locate Access.pm
/home/httpd/twiki/lib/TWiki/Access.pm
aims-07:~# /etc/cron.daily/find
aims-07:~# locate Access.pm
aims-07:~#

What are the differences between these and why does the daily cron job
find less files than running updatedb?  I have a standard install and
have not modified either /etc/updatedb.conf or /etc/cron.daily/find.
I see the same behaviour on both stable and testing installs.

Thanks.
