Hmm, it wouldn't be completely unreasonable to use /var/cache.

But since the file doesn't represent a cache of the state, but the 
actual state (modifying the file would modify the state of the program).

Since /var/lib is "variable state information" (according to FHS 3.0), I 
think it makes more sense, but I'm not sure about it.  I've never used 
it before.
