I'd like to suggest also the ability to store arbitary "comments" for 
users.  I really miss being able to say "Changed this to 6 (from 3) to 
make the foo feature work." or perhaps "The Foo installer changed this 
value to "narf" during install").  Looking through /etc on a large 
machine that's been installed for a while you see lots of comments made 
by programs, or humans explaining why various bits of a config have been 
changed.  I miss being able to set and read these on software managed 
config systems.
