My OCD wants you to name this matrix_guest instead of guest_matrix. Simply
because then "matrix" and "matrix_guest" will be grouped together when doing
an ls on the parent directory. As a system admin, its the little things that
make the difference :) Please consider... though I won't withhold an R-b for
it.
