The nice thing about using mtree is that it uses a data file format to 
hold the parameters -- the owner, group, permissions, etc, rather than 
encoding it in a script.  I.e., that it is explicitly encoded information 
rather than implicit.  Another nice thing about it is that it doesn't rely 
on creating the directory at run-time, but assumes it is part of the base 
install/configuration, and always present.  I'm not generally a fan of 
setting up directory hierarchies by encoding that into scripst and 
programs, but rather making it an explicit entry in our existing directory 
database.
