# /etc/quagga/daemons
# This file tells the quagga package which daemons to start.
#
# Entries are in the format:=(yes|no|priority)
# 0, "no" = disabled
# 1, "yes" = highest priority
# 2 .. 10 = lower priorities
# Read /usr/share/doc/quagga/README.Debian for details.
#
# Sample configurations for these daemons can be found in
# /usr/share/doc/quagga/examples/.
#
# ATTENTION:
#
# When activation a daemon at the first time, a config file, even if it is
# empty, has to be present *and* be owned by the user and group "quagga", else
# the daemon will not be started by /etc/init.d/quagga. The permissions should
# be u=rw,g=r,o=.
# When using "vtysh" such a config file is also needed. It should be owned by
# group "quaggavty" and set to ug=rw,o= though. Check /etc/pam.d/quagga, too.

Ehternet bridge makes the network part of migration easy, since no
special routing technology is required. Just connect the two HNs with
(virtual) switch or hub, then the new VE cannot located by ARP.
OpenVZ migration is very easy, with SSH keys, it get the job done with
just one command.
So, with this fundamental migration works, it's time to implement some
watchdog or monitoring mechanism for automatical migration. With it,
it's possible to set up a VPS farm which supports numbers of VEs
balanced between HNs dynamically.

俺给个中文翻译吧：
1. 把马桶坐垫全掀起，往马桶里倒 1/8 瓶宠物香波。（译者注：当然在此
之前您至少要冲过马桶吧。）
2. 抱起您的猫，温柔地把它带到卫生间。（译者注：每次请只洗一只猫，猫
的大小须能放进马桶里而冲不进下水道。）
3. 趁您的猫正在爽的时候，把它放进马桶并把马桶盖全盖上。必要的话，您
需要站到坐垫上。（译者注：如果这个动作有难度而您的体重足够的话，
坐着也可以）。
4. 你的猫会给自己抹好香波。不用担心马桶里传来的噪音，您的猫正爽着
呢。
5. 冲洗马桶 3 到 4 次以进行洗涤和漂洗。
6. 找个人把您家大门打开，确保从卫生间门口到大门的通道畅通无阻。
7. 用您最敏捷的身手跳到马桶后面，迅速掀起马桶盖。
8. 您的猫会像火箭一样冲出马桶，窜出卫生间，狂奔至某个可以把自己弄干
的地方。
9. 这样，您的马桶和猫都干净了。
