"This section is optional.  If the intended user is not a programmer and does "
"not plan to do any debugging on the system software, the system size can be "
"decreased by about 2 GB by removing the debugging symbols from binaries and "
"libraries. This causes no inconvenience other than not being able to debug "
"the software fully anymore."

"本节是可选的。如果系统不是为程序员设计的，也没有调试系统软件的计划，可以通过"
"从二进制程序和库移除调试符号，将系统的体积减小约 2 GB。除了无法再调试全部软件"
"外，这不会造成任何不便。"

"Most people who use the commands mentioned below do not experience any "
"difficulties. However, it is easy to make a typo and render the new system "
"unusable, so before running the <command>strip</command> commands, it is a "
"good idea to make a backup of the LFS system in its current state."

"大多数使用以下命令的用户不会遇到什么困难。但是，如果打错了命令，很容易导致新"
