The gzexe shell script, which is used to create self-extracting
	compressed executables, does not detect its own dependency on
	/bin/sh, and will attempt to compress it if asked. It does however
	detect dependency on chmod, rm, sleep etc. and refuses to compress
	them.

	If you attempt to compress /bin/* to conserve space on a system
	with a small disk (in my case, a printer server with a 120 MB
	disk), gzexe will trash sh, which makes it impossible to uncom-
	press and use any other compressed binary (e.g. cp, in order to
	'cp sh~ sh')

	It is also possible that the same problem exists for echo and sed
	(which are used by the decompression script, but not checked for
	by gzexe)

Fix: 

Run this shell script as root:
	
#!/bin/sh
patch -n `which gzexe` - <<EOF
77c77
<   gzip | tail | chmod | ln | sleep | rm)
---
>   sh | gzip | tail | chmod | ln | sleep | rm)
EOF

	This will cause gzexe to check if you are trying to compress sh.
How-To-Repeat: 
	# gzexe /bin/sh
	Segmentation fault - core dumped
