That depends.

George Goble used to refer to people who had really
long .cshrc, .login, or .profile files as users with
their own /vm{$USERNAME}.

(where {$USERNAME} is substituted appropriately).

On a relatively fast machine, I had a 30 line .cshrc,
which he always referred to as /vmkulkis.



[For those who don't get it... "vm" is the traditional
prefix for all Unix kernels which support virtual memory...
this goes back to at least /vmunix on 4.1 BSD, and probably
even earlier (since Unix was ported to the IBM 370 before
it as ported to the VAX-11].
