任何系统的彻底修检都应考虑到已有的系统。其中包括让尽可能多的资源复用,和保证组成系统的各个部分协调无碍。以下的学习案列会介绍一个将设备向 Linux 迁移的通用技术框架。

3.1. 在异构环境中共存


3.1.1. 和Windows机器整合


3.1.2. 和OS X机器整合

OS X machines provide, and are able to use, network services such as file servers and printer sharing. These services are published on the local network, which allows other machines to discover them and make use of them without any manual configuration, using the Bonjour implementation of the Zeroconf protocol suite. Debian includes another implementation, called Avahi, which provides the same functionality.
In the other direction, the Netatalk daemon can be used to provide file servers to OS X machines on the network. It implements the AFP (AppleShare) protocol as well as the required notifications so that the servers can be autodiscovered by the OS X clients.
Older Mac OS networks (before OS X) used a different protocol called AppleTalk. For environments involving machines using this protocol, Netatalk also provides the AppleTalk protocol (in fact, it started as a reimplementation of that protocol). It ensures the operation of the file server and print queues, as well as time server (clock synchronization). Its router function allows interconnection with AppleTalk networks.

3.1.3. Integration with Other Linux/Unix Machines

Finally, NFS and NIS, both included, guarantee interaction with Unix systems. NFS ensures file server functionality, while NIS creates user directories. The BSD printing layer, used by most Unix systems, also allows sharing of print queues.
