>Release:        FreeBSD 2.2-CURRENT i386
>Environment:

	'make install' with a shortage of disk space

>Description:

	install(1) removes the target file if the disk becomes full during
	the operation.

>How-To-Repeat:

	on a machine with a shortage of space in /
	do a 'make install' in /usr/src
	notice that /bin/sh or /sbin/dump (for instance) can get clobbered

>Fix:
	
	relink to the old copy of the file if it still exists, as is likely
	the case for /bin/sh

	or:

	always keep a reference to the old copy, and relink to it on failure.
