Openmediavault 6的安装和升级

因为OMV5在SMB限制Quota大小的问题时发现omv已经发布了6版本，于是想到可能升级后可以解决这个问题，事实上设置中已经可以更新了，效果还未测试。

如果你的OMV版本 < 6那么可以用下面的命令升级：

apt update
apt upgrade -y
omv-update
omv-upgrade

如果你已经是最新版的omv，那么需要使用最新版的Debian11才可以安装，因为它依赖PHP7.4，其他系统同理，那么在运行前面的命令前需要先升级debian的大版本到11后再执行即可。

如果是初次安装，或者打算手动安装可以参考下面的代码：

cat <> /etc/apt/sources.list.d/openmediavault.list
deb http://packages.openmediavault.org/public shaitan main
# deb http://downloads.sourceforge.net/project/openmediavault/packages shaitan main
