I use -[NSUserDefaults addSuiteNamed:] to add the defaults from a

fine, except I want to remove a certain key/value pair from the suite.
Is there any way to do this? The best plan I can come up with so far
is to read the old defaults from its plist into an NSMutableDictionary
then add all the keys to the app domain (except the one I want to
remove). But there does not seem to be any API to get
~/Library/Preferences/foo.plist in a nice localizable way...
Definitely don't access the .plist file directly.
One approach is to drop down to Core Foundation's CFPreferences API.
Another is to use the "persistent domain" capabilities of
NSUserDefaults. Pull in the dictionary for the domain, make a
mutable copy, modify it, and then write the whole domain back out.
