    SubjectIs there a "make hole" (truncate in middle) syscall?
    Date
    You can make a file with a hole by seeking past it and never writing to that 
    bit, but is there any way to punch a hole in a file after the fact? (I mean
    other with lseek and write. Having a sparse file as the result....)

    What are the downsides of holes? (How big do they have to be to actually save
    space, is there a performance penalty to having a file with 1000 4k holes in
    it, etc...)
