我的理解是d表示是一个守护进程,就象vsftpd named 这些都是一种命名习惯.
就象脚本都习惯用sh 做后缀一样

像httpd后面的d是什么意思?
被动语态,ed的简写,
意为
1,被服务的;
2,为...服务;

daemon=demon
1. 恶魔,恶鬼
2. 恶人;凶恶的人
3. 邪恶的事物;恶劣的影响
4. 精力充沛的人;高手;热心


daemon  
DEFINITION - A daemon (pronounced DEE-muhn) is a program that runs continuously and exists for the purpose of handling periodic service requests that a computer system expects to receive. The daemon program forwards the requests to other programs (or processes) as appropriate. Each server of pages on the Web has an HTTPD or Hypertext Transfer Protocol daemon that continually waits for requests to come in from Web clients and their users.

In mythology, a daemon, according to Webster's, was "an attendant power or spirit."

Daemon can be confused with demon, which has a different but similar meaning. The New Hacker's Dictionary says that a daemon is a program that runs by itself directly under the operating system whereas a demon is part of a larger application program.
