### it's freebsd customsized setup script. it could run on "sh" now.
### it setup xfce, dual video card (nvidia and intel), cjk fonts, fcitx5, firefox and chromium.
### (fcitx5 may miss some env settings. install zh-ibus-rime and then remove ibus and re-login, it works.)
### i perfer modify "/usr/local/share/rime-data/default.yaml" to use " - schema: wubi_trad".
### for yourself, it needs to modify variable value:  YOUR_USER_NAME, and values in XORG_CONF_FILE_NAME config. e.g. BusID
### use command: "pciconf -lv | grep -A 4 vgapci"


### 在輸入用戶名校驗處做了更改，可以運行在 Bourne Shell 卽 sh 上
### changed user name verify implement to run on bourne shell (sh) by change the first line "bash" to "sh".

### 必須要有一個 freebsd-boot 分區（類型），而且必須是 512KB 大小。
### must have a patition of freebsd-boot with size 512KB only.
### 組合鍵 ctrl+alt+f1 能回到 console 界面
### switch to console by ctrl+alt+f1
### 由於 freebsd 安裝時沒有格式化分區的功能，所以重裝系統時可用改變分區格式的方法 freebsd-zfs 和 freebsd-ufs 間輪替，或刪除分區再重建。
### cause freebsd does't have format partition option while installing, to install a "clean" system, you can delete and recreate the partition.

# sharing swap space between Linux and FreeBSD
# 由於 FreeBSD 可以使用任何形式的分區作爲 swap 分區。而 Linux 需要在 swap 分區上設定一個特殊標識。
# vi /etc/fstab
# add line below for swap patition (e.g. hda6 is swap patition)
# /dev/hda6 none swap sw 0 0

# While FreeBSD can use any type of partition as swap space, Linux needs a special signature in the swap partition. This signature is made by mkswap. FreeBSD ruins this signature when it uses the shared swap partition, so you will have to run mkswap each time you boot into Linux. To do this automagically you have to find the script that runs swapon at boot time. In Red Hat Linux it is /etc/rc.d/rc.sysinit. Put the following line into that file just before swapon -a:

# awk -- '/swap/ && ($1 !~ /#/) { system("mkswap "$1"") }' /etc/fstab
