这是一个 Bash 脚本，用于从 Red Hat Linux 发行版的 ISO 文件或 FTP 树结构中创建可启动的 DVD ISO 映像。脚本会检查输入目录中的 ISO 文件，并将必要的文件复制到指定的位置以准备生成新的 DVD 映像。

# A quick hack that will create a bootable DVD iso of a Red Hat Linux
# Distribution. Feed it either a directory containing the downloaded
# iso files of a distribution, or point it at a directory containing
# the "RedHat", "isolinux", and "images" directories.

# This version only works with "isolinux" based Red Hat Linux versions.

# Lots of disk space required to work, 3X the distribution size at least.

# GPL version 2 applies. No warranties, yadda, yadda. Have fun.
