安装时：

sudo apt-get install \
    linux-image-extra-$(uname -r) \
    linux-image-extra-virtual

我正进入（状态：

W: mdadm: /etc/mdadm/mdadm.conf defines no arrays.

我发现其他人也有类似的问题：apt-get update mdadm 可怕的警告

所以我按照说明操作：

/usr/share/mdadm/mkconf > /etc/mdadm/mdadm.conf

然后：

update-initramfs -u

但输出是：

update-initramfs: Generating /boot/initrd.img-4.10.0-30-generic
W: mdadm: /etc/mdadm/mdadm.conf defines no arrays.

当我运行时，docker &我得到：

INFO[0000] libcontainerd: new containerd process, pid: 3091 
INFO[0000] [graphdriver] using prior storage driver: aufs 
INFO[0000] Graph migration to content-addressability took 0.00 seconds

我也收到所有这些警告：

WARN[0000] libcontainerd: client is out of sync, restore was called on a fully synced container (8564990571b56c26f32872031507e77f786b870b27ed3f0b80eebe127ce65164).

我在 GCP 中使用 Ubuntu 17.10 VM。为了防止我的服务器的 IP 被欺骗，我在我的 /etc/host.conf 文件中做了以下更改：

更改自：

# The "order" line is only used by old versions of the C library.
order hosts,bind
multi on

到

# The "order" line is only used by old versions of the C library.
?order bind,hosts
?nospoof on

但这给出了以下错误：

/etc/host.conf: line 2: bad command `?order bind,hosts'
/etc/host.conf: line 3: bad command `?nospoof on'

出了什么问题？
