It might be (ever so) slightly better here to use Perl's backtick
operator to slurp the output rather than declaring $/ local prior
to calling a function in the same block:

	foreach my $bin (@_initrd_binaries) {
	    if (-f "$dir/bin/$bin") {
                $_ = `file $dir/bin/$bin`;
		if (/ELF.*executable, (.+?),/) {
		    return _elf_arch_to_canonical ($1);
		}
	    }
	}

Having read through the rest of the code, that's the only thing
I could find to comment on... :-)
