Note that the tar and cpio commands are wrappers to pax.
That's fine for just extracting and creating .tar and cpio
archives. If you hace to do anything more complex
(particularly if you're trying to do a system audit using
th GNU tar -d (--diff) feature then you might need to
get a "real" copy of these.
One trick I've used with Tom's is to customize my
startup scripts to configure the booted system into a
reserved network IP address (reserved at one-per-floppy) and
to mount up a public NFS mount (read-only export).
With the proliferation of glibc based systems I'd have to
add a part that would append /mnt/share/lib and run
ldconfig.

You can also use dd if=/dev/[sh]da of=/root/bak/mbr.bin \
count=1 to save a binary copy of your boot record and
partition table to some file (modify this command to suit
your needs and DON'T FOREGT THE count= option!).
Of course this assumes that you have a local network and
sufficient control over some other systems on it.
