Thanks for writing that.  Some minor points:

Hmm, where did that "65535" come from?  I don't know of any limit of
65535 bytes (presumably you meant bytes, not characters) that is
required by POSIX.

Also, there are moves to change the pax format (so far in an
upward-compatible way, but you never know....).  Perhaps you should
mention that "tar-pax" is intended to be the most recent version of
the pax interchange format, not necessarily the 2001 version.  (This
problem probably afflicts the GNU tar documentation as well....)

Wouldn't it be safer to use 'cpio -H tar -i' rather than 'cpio -i'?
The latter autodetects, but I worry that autodetection isn't infallible.
(I don't know about cpio to be sure here.)
