supermin5 一個工具，運行命令man supermin能夠查看關於這個工具的基本信息。

 

1. NAME

2. supermin - Tool for creating supermin appliances

3.  

4. SYNOPSIS

5. supermin [-o OUTPUTDIR] --names LIST OF PKGS ...

6. supermin [-o OUTPUTDIR] PKG FILE NAMES ...

7.  

8. DESCRIPTION

9. Supermin is a tool for building supermin appliances. These are tiny appliances (similar to virtual machines), usually

10. around 100KB in size, which get fully instantiated on-the-fly in a fraction of a second when you need to boot one of

11. them.

12.  

13. Originally "fe" in "febootstrap" stood for "Fedora", but this tool is now distro-independent and can build supermin

14. appliances for several popular Linux distros, and adding support for others is reasonably easy. For this reason,

15. starting with version 4, we have renamed the tool "supermin".

16.  

17. Note that this manual page documents supermin 4.x which is a complete rewrite and quite different from febootstrap 2.x.

18. If you are looking for the febootstrap 2.x tools, then this is not the right place.
