This is not the goal.  this is about use any gzip present on the system, 
so you can survive any config:

- use /rescue/gzip without /bin/gzip and without /stand (HEAD/RELENG_5)
- use /stand/gzip  without /bin/gzip and without /rescue (RELENG_4)
- use /bin/gzip as default when this may be avaiable.

Well, I'm not using this rigth now.  I'm sharing the rootfs as filled by 
sysinstall.  Also, you may want use a mfs based rootfs (via tftpboot).

Also, I think that we can't truss actual initdiskless docs/scripts.  We 
need brand new ones.
