[Pkg-xen-devel] [PATCH 11/16] debian/xendomains.init: Pipe xen-init-list instead of tmp file

[Elliott Mitchell]

Shell syntax is has some funky behavior in some areas/ways.  For these
sections /usr/lib/xen-common/bin/xen-init-list should be piped to the
loop, rather than creating a temporary file.  This is also pure-Bourne
shell syntax, rather than requiring Bash.
