我这里测试的结果是有的参数不能用，所以手动修改了一些脚本内容，我定义的默认安装路径是：/home/oblivecd，请根据自己的分区大小情况调整，经测试正常生成了OpenBSD 4.8 AMD64 版的livecd。
第一个附件是原始脚本，第二个是我修改的。
这里是修改后的脚本：

Welcome to OpenBSD: The proactively secure Unix-like operating system.
Please use the sendbug(1) utility to report bugs in the system.
Before reporting a bug, please try to reproduce it with the latest
version of the code. With bug reports, please try to ensure that
enough information to reproduce the problem is enclosed, and if a
known fix for it exists, include that as well.

Packages can be managed easily with the help of several utilities, also referred to as the pkg* tools:
* pkg_add(1) - a utility for installing and upgrading software packages.
* pkg_delete(1) - a utility for deleting previously installed software packages.
* pkg_info(1) - a utility for displaying information about software packages.
* pkg_create(1) - a utility for creating software packages.
To fetch packages from the OpenBSD mirror, use the following command:
# export PKG_PATH=$(echo $PKG_PATH | sed 's#\ ##g')
If you want to try out your software, you may encounter the following error message:
program: can't load library 'somelibrary'
To get rid of it, there is the following workaround:
export LD_LIBRARY_PATH=/usr/local/lib
