Problem Description: 

	Data loss when using cpio copy-in under specific conditions with
	2 files each having more than 1 link each are copied-out and the
	inodes of these 2 files are the "same" when looking at the lower
	16 bits.  When these files are copied-in, these filenames are all
	linked to the same file, i.e., the data from one of the original
	files has been silently lost.

INSTALL:

	As root, make a backup copy of cpio:

	mv /usr/bin/cpio /usr/bin/cpio.fcs
	
	Now install the patched version of cpio:

	mv `arch`/{4.1,4.1.1,4.1.2}/cpio /usr/bin/cpio
	chown root.staff /usr/bin/cpio
	chmod 755 /usr/bin/cpio


ADDENDUM:
