>Description:
I ran "make installworld" from a ready built BETA6 while / was low on space.
Make installworld crashed in the middle of its process and left me with
a system that had no libc.so.5.

I have no "INSTALL"-related options in /etc/make.conf.
	
>How-To-Repeat:
1. build world and install rescue so you can back out
2. fill / (perhaps with dd if=/dev/zero of=/deleteme) so it
   cannot hold another libc.so.5 copy
3. install world

Depending on the exact amount of free space on / in step #2 and #3, you may not
hit a problem with installing libc.so.5 but some other installation.

to recover, use: /rescue/cp /usr/obj/usr/src/lib/libc/libc.so.5 /lib
	
>Fix:
Let the installation for ESSENTIAL files use the -S flag so that there is
always a usable copy of these files in place.
