Is Chromium OS is a GNU/Linux distribution or is it a non-GNU Linux-based operating system like Android, webOS or Syllable Server? Does Chromium OS use GNU C Library, GNU coreutils etc., or maybe it has its own native UNIX core utilities like Android before version 6.0 (in Android some of core utilities were taken from NetBSD) or it uses for example Toybox, like Android from version 6.0 onwards? I tried to search the source of Chromium OS, looking for GNU coreutils and glibc, but I can't find them there.
ChromeOS is NOT a GNU/Linux distro. However, ChromeOS IS a distribution of Linux. The basic elements of a GNU/Linux system are described here: https://unix.stackexchange.com/a/88625/159449.
ChromeOS ships with the following:
- Linux Kernel
- Bash ( although it was not until much later in the ChromeOS development process and it is still limited to certain hardware).
But ChromeOS does not ship with the following:
and ChromeOS also prevents the normal user from taking steps to add those items to the OS. Therefore, I would not classify ChromeOS as a distribution of GNU/Linux.
As per Wikipedia:
Chrome OS is an operating system designed by Google and based upon the Linux kernel.
If you read the design section, it's a typical "Linux/BSD core services, tweaked for specific reasons, with a custom and proprietary UI and service architecture."
It is not a Linux distribution, even in the loosest sense.
This site states that both Chromium OS and ChromeOS are GNU/Linux distributions based on Gentoo: https://wiki.installgentoo.com/index.php/ChromeOS
