我經常為舊版本(Debian 和 Ubuntu,包括 oldoldstable)重建軟體包(主要是 Debian)。其中一些軟體包使用該lsb_release
命令來確定當前的發行版,以便更改行為Build-Depends
等。
我有多分佈與CPU架構cowbuilder設置,但是要準備來源套件(然後在與目標發行版相符的乾淨環境中建置),我仍然需要執行以下操作:
dpkg-source -x openjdk-7_7u55-2.4.7-1~deb7u1.dsc
cd openjdk-7-7u55-2.4.7
dch --bpo
dpkg-buildpackage -S
該dpkg-buildpackage -S
步驟創建一個來源*.dsc
執行 clean 目標後(在許多套件中重新產生 debian/control)。但為此,lsb_release
輸出需要是,例如,squeeze
甚至lenny
。
從我在 Debian/m68k 上的工作我知道我可以創建一個/etc/lsb-release
包含魔法的、記錄不足的行的文件來控制 的輸出lsb_release
,否則會查看 APTsources.list
文件preferences
等以確定分發。但是沒有簡單的方法可以讓輸出鏡像另一個現有的發行版。
有沒有人收集這類文件來鏡像目標發行版?

若要欺騙 lsb_release,請使用以下腳本:
#!/bin/bash
Help()
{
echo "
Usage: lsb_release [options]
lsb SPOOFER!!!
put this in your home bin dir, then do:
chmod a+x ~/bin/lsb_spoof
cd /usr/bin
mv lsb_release lsb_releaseBAK
ln -s /home/user/bin/lsb_spoof lsb_release
Options:
-h, --help show this help message and exit
-v, --version show LSB modules this system supports
-i, --id show distributor ID
-d, --description show description of this distribution
-r, --release show release number of this distribution
-c, --codename show code name of this distribution
-a, --all show all of the above information
-s, --short show requested information in short format"
}
