如何识别嵌入式 Linux 发行版？

Question

我正在尝试识别嵌入式 Linux 发行版。以下是我到目前为止输入的命令：

$ uname -a
Linux LIN-SRV-EMB01 3.10.105 #25556 SMP Sat Aug 28 02:14:22 CST 2021 x86_64 GNU/Linux synology_bromolow_rs3412rpxs

$ which lsblk lscsci lshw lspci dmidecode

EDIT0：尝试了另外两个命令：

$ strings $(ps -p 1 -o cmd= | cut -d" " -f1) | egrep -i "ubuntu|debian|centos|redhat" -o | sort -u
-sh: strings: command not found
[remoteserver] $ ssh embedded-linux 'cat $(ps -p 1 -o cmd= | cut -d" " -f1)' | strings | egrep -i "ubuntu|debian|centos|redhat" -o | sort -u
ubuntu

EDIT1：尝试了另外三个命令：

$ which initctl && initctl --version
/sbin/initctl
initctl (upstart 1.13.2)

$ which systemctl && systemctl --version
$ cat /sys/class/dmi/id/product_name

$

EDIT2：又尝试了一个命令（特定于 Synology）：

$ grep productversion /etc/VERSION
productversion="6.2.4"

EDIT3：以防万一有人想识别硬件：

$ uname -u # Specific to Synology ?
synology_bromolow_rs3412rpxs

$ sudo dmidecode -t system | grep Product
        Product Name: To be filled by O.E.M.
$

$ cat /sys/devices/virtual/dmi/id/product_name
To be filled by O.E.M.
$

EDIT4：在另一个 Synology 上，我得到：

$ uname -u
synology_broadwell_rs3618xs

我猜它是基于Ubuntu+upstart的。

EDIT5：可以使用此 Observium 脚本或此 LibreNMS 脚本来识别 Distrib 。

我还可以使用哪些其他命令来更深入地了解？

输出uname -a将其识别为 Synology 设备。此类设备运行Synology DiskStation Manager。这是基于 Linux 的，但它不像运行 \xe2\x80\x9ctraditional\xe2\x80\x9d Linux 发行版的典型 Linux 系统那样进行管理。它有自己的包管理器 ，SynoCommunitysynopkg为其提供了第三方包。DiskStation CLI 指南介绍了 DSM 中可用的一些管理工具。

如果您\xe2\x80\x99 对在此类设备上自动执行管理任务感兴趣，您可能会发现Synology\xe2\x80\x99s 中央管理系统很有用。
