The static root option exists for people with special requirements:
   * Use a lot of shell scripts
   * Have very high performance requirements for those scripts
   * Does not use LDAP, NIS, or other networked directory services
     (I want to move NIS out of libc.  Its privileged position
     relative to LDAP and other services is rather dated.)

E.g., someone with a standalone server that's using
/bin/sh to run CGIs would be well advised to compile
a static /bin/sh.  Fortunately, that's easy to do.

User shell scripts do rely on tilde expansion.  Having
that break in any environment relying on networked directory
services is a pretty serious loss of functionality.
