rpm – 重命名munin包时发布postun脚本的问题

我正在重命名munin 2.0软件包,在SPEC文件中我必须废弃原来的munin软件包.

当将现有的1.x munin软件包替换为munin-node的postun scriptlet的一部分时,它会删除munin用户.

postuninstall scriptlet (using /bin/sh):
if [ $1 -eq 0 ]; then
    /usr/sbin/userdel munin || logger -t munin/rpm "User "munin" could not be deleted."
#       /usr/sbin/groupdel munin || logger -t munin/rpm "Group "munin" could not be deleted."
fi

当我替换现有的munin 2.0软件包时,postun会删除plugins目录的内容.

postuninstall scriptlet (using /bin/sh):
if [ "$1" = "0" ]; then
   [ -d /etc/munin/plugins ] && 
find /etc/munin/plugins/ -maxdepth 1 -type l -print0 | 
   xargs -0 rm || :
fi

由于yum安装新软件包,然后运行旧软件包的帖子,并且在这两种情况下$1 = 0,它将在我的rpms安装后运行脚本.有办法解决这个问题吗？
