# i.CompCpio
#
# This shell script uncompresses and installs files archived in
# old-style WOS packages using the utilities cpio and compress. It
# looks in the PKGSRC directory for the archives which may be called
# out in one of eight ways :
#
#   reloc.cpio.Z    relocatable paths, less old style
#   root.cpio.Z absolute paths, less old style
#   reloc.cpio  relocatable paths less old style, not compressed
#   root.cpio   absolute paths, less old style, not compressed
#   reloc.Z     relocatable paths, old style, compressed
#   root.Z      absolute paths, old style, compressed
#   reloc       relocatable paths, old style, not compressed
#   root        absolute paths, old style, not compressed
#
# stdin carries the source directory as the first entry followed by the
# paths of the files to be installed as indicated in the pkgmap. Since
# all operations take place from the declared base directory, both relative
# and absolute paths will install correctly. There are three methods and
# since speed is of the essence, we skip straight to the right one :
#
#   If it's an initial install
#       do a full cpio for each archive
#   else
#       If there's only the reloc archive
#           make a file list, rm executables, do a selective cpio
#       else
#           rm executables, do a full cpio for each archive
#
# Since the old-style archives contain no execute permissions, this
# script saves the executables it requires so it can clean up after
# unloading the archive. If /usr/lib/ld.so or .so.1 is included in the
# package, no cleanup will be possible (nothing will run) so we clean
# up first and then unload the entire archive without a file list.
