Alex 转了下面 Linus 的邮件，这封邮件被几乎所有介绍 Linux 书收录，不难看到，但我仍然愿意在这里再帖一下：
Hello everybody out there using minix -1991 年 8 月 25 日，我刚刚开始上小学二年级，在我家乡的凤凰完小；11 年之后的 2002 年 10 月，我开始看 Linux 方面的书； 14 年后的 2005 年 7 月，我进入现在这家公司，做嵌入式 Linux 开发； 15 年后的 2006 年 8 月，我决定为 Linux 做点什么。
I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu) for 386(486) AT clones. This has been brewing since april, and is starting to get ready. I'd like any feedback on things people like/dislike in minix, as my OS resembles it somewhat (same physical layout of the file-system (due to practical reasons) among other things).
I've currently ported bash(1.08) and gcc(1.40), and things seem to work. This implies that I'll get something practical within a few months, and I'd like to know what features most people would want. Any suggestions are welcome, but I won't promise I'll implement them :-)
PS. Yes - it's free of any minix code, and it has a multi-threaded fs. It is NOT protable (uses 386 task switching etc), and it probably never will support anything other than AT-harddisks, as that's all I have :-(.
