If sorcery now requires the use of locate then shouldn't it be the developer's job to install such a cron script by default? Otherwise this becomes a big annoyance for the user.

Sorcery doesn't use locate, it generally uses find... if you were asking
why sorcery uses it.
If you were asking the more general question, "Why use locate?" Here's
why:
Updatedb can be scheduled to run at a time when you're not using the
computer (5am on Sundays is usually good for me), this keeps the db up
to date, and locating a file takes a fraction of a second. It takes
about as long to do an updatedb as it takes to do a 'find /' and with
locate you can do multiple lookups without having to search the whole HD
each time.

But why use locate? I never run updatedb and after awhile the db gets horribly out of synch. Updatedb also takes a ridiculous amount of time to run. What is locate doing in sorcery? Why not use find?

locate is provided by findutils, which is still part of the base system.
You will need to run updatedb at least once as root to create the
locatedb file. I don't think it runs it automaticaly, and I don't think
it sets up a cron job to do it either.

It looks like the latest devel sorcery is using `locate.' I can see the
messages
that /var/cache/locatedb is missing. I don't think locate is part of the
basesystem. Any reason for this?
Thanks!
