With UFS/AUFSdiskd the cache is stored in a directory tree with
individual files per item. Reducing the size results in files being
deleted from disk an the total size shrinks naturally without any
special action by Squid.
Rock on the other hand has all content stored inside one file. That file
gets initialized with the space configured and maybe grown if needed.
But there is nothing I'm aware of to reinitialize it on smaller sizes
being configured. Reducing the size does reduce the size of stuff using
space *inside* the database file, but AFAIK not the file itself.
