Does crunchgen have any option on prefixing the PATH with /rescue?

"/rescue/tar z" uses /usr/bin/gzip instead of /rescue/gzip. (Same with 
bzip2.)

My userland was corrupted due to bad systinst using scratched CD.

I worked around by using "/rescue/gzcat foo | /rescue/tar xvf -"

But it would be nice if /rescue's tar can handle that automatically.

I see CPPFLAGS.foo.c and OVERRIDEOBJS in src/rescue/Makefile. I haven't 
used it yet, but maybe that could be used with:

CPPFLAGS.options.c+=	-GZIP_CMD=\"${RESCUEDIR}\/gzip"
and for BZIP2_CMD also.

And src/bin/pax/options.c be modified to not redefine these.

Any comments before I do this?

Where is CPPFLAGS.foo.c documented? Where is OVERRIDEOBJS documented? (Do 
I need OVERRIDEOBJS?)
