28# i.CompCpio
29#
30# This shell script uncompresses and installs files archived in
31# old-style WOS packages using the utilities cpio and compress. It
32# looks in the PKGSRC directory for the archives which may be called
33# out in one of eight ways :
34#
35#	reloc.cpio.Z	relocatable paths, less old style
36#	root.cpio.Z	absolute paths, less old style
37#	reloc.cpio	relocatable paths less old style, not compressed
38#	root.cpio	absolute paths, less old style, not compressed
39#	reloc.Z		relocatable paths, old style, compressed
40#	root.Z		absolute paths, old style, compressed
41#	reloc		relocatable paths, old style, not compressed
42#	root		absolute paths, old style, not compressed
43#
44# stdin carries the source directory as the first entry followed by the
45# paths of the files to be installed as indicated in the pkgmap. Since
46# all operations take place from the declared base directory, both relative
47# and absolute paths will install correctly. There are three methods and
48# since speed is of the essence, we skip straight to the right one :
49#
50#	If it's an initial install
51#		do a full cpio for each archive
52#	else
53#		If there's only the reloc archive
54#			make a file list, rm executables, do a selective cpio
55#		else
56#			rm executables, do a full cpio for each archive
57#
58# Since the old-style archives contain no execute permissions, this
59# script saves the executables it requires so it can clean up after
60# unloading the archive. If /usr/lib/ld.so or .so.1 is included in the
61# package, no cleanup will be possible (nothing will run) so we clean
62# up first and then unload the entire archive without a file list.
