The official recommendation is actually to checkout to /Library :p

I assume ‘recommendation’ then refers to one of the suggestions in  
the recent “how do you manage customizations”-thread!?!

rsync will not work, because when TM saves a new file, it uses a  
filename based on the name of the item. But when later updating the  
file, it preserves the filename.

This means that a lot of the default bundle items have older names on- 
disk, but when you customize one, it will get an updated name in ~/ 
Library. So the filenames will not (always) be the same.

Because they have the same UUID. That’s the only thing TM cares about.

It’s not straight-forward. You would need to generate a map of UUID  
=> filename from scanning all the default bundles.

Then iterate over your custom stuff, lookup the UUID in this map, and  
rename it to that filename. First then, will you be able to use rsync.

So the essence is that your custom stuff do not have the original  
filenames, so they must be renamed to take the place of the files in  
svn, and the original filename can be found by checking the UUID of  
the item, and finding out which original file has that UUID.

The Info.plist is only used to set the ordering of items (and by  
marking default items as deleted, as they can’t be removed from  
disk). So in practice this file plays no vital role at all.
