The cache manager will automatically select values for any of the
parameters you can set on the command line if you don't provide them --
there are no required arguments to afsd.
The values for the -blocks, -cachedir, and -mountdir options are taken from
the cacheinfo file; you can get away without that file if these are
specified on the command line.
If any of the -files, -stat, -chunksize, and -dcache parameters are not
given, appropriate values are computed based on the cache size and those
values that are given.
The default values for -rootvol, -daemons, -volumes, and -files_per_subdir
are fixed, and the default value for -confdir is determined at compile time.
