[Pkg-xen-devel] [PATCH 13/16] d/shuffle-boot-files: Simplify loop structure

[Elliott Mitchell]

Rather than changing into the work directory and then running find,
instead simply run find and strip off the directory name later.  Since
the directory name was being re-added to the source filename later, this
reduces complexity.  Instead the work directory name needs to be stripped
off the target filename.

Put another way, remove all processing of source filename and do more
processing of target filename.

While at it use structures which conform to POSIX, allowing the use of
/bin/sh instead of bash.
