So, portion ChromeOS is virtually Linux astatine its core, it's a peculiar tightly-controlled and highly-specialized implementation of Linux. ChromeOS is astir arsenic related to Linux arsenic immoderate of the assorted devices similar crippled consoles oregon TVs that person bundle based connected Linux. Heck, you tin adjacent adhd Android to the extended Linux family.

These days, ChromeOS tin tally Linux software, but to marque that imaginable rather a batch had to beryllium added to the operating system.

However, I've daily-driven Chromebooks before, and for a batch of radical there's truly thing that they typically bash connected their Linux (or Windows, oregon macOS) computers that they can't bash connected ChromeOS.
