Hmm, it is easier to have a wait in case the targeted FS is FAT. current code
has enough functionality to do that. but the problem is that wait itself seems
not meaningless so that fc-cache isn't a singleton process and easy to conflict
with the multiple processes on current code base.
Though it might be better than do nothing.
If there are any better idea, the suggestions are welcome.
I may go ahead with checking fs type for a workaround to see if fc-cache should
wait for 2s or not otherwise.
