Linux is just an app that runs in macOS and windows.

  There's an app called iSH on TestFlight that gives you precisely that for iOS as well ;)

    iSH is actually pretty great, considering the compromises that must be made to get a local shell on an iPhone. Just wish it was debian based

  Ignoring the "just" (it is much more than just that), running one OS under another is scarcely a new thing. In early 1977, Unix V6 was an app that run on Interdata OS/32 [1]. (Within a few months, it had gained the ability to run directly on the Interdata 7/32 hardware, without the need for the rather primitive OS/32 operating system to sit under it.) AT&T's 1979-1980 port of Unix to IBM mainframes ran it on top of the TSS/370 operating system [2]. (TSS was IBM's original, and ultimately unsuccessful, attempt to deliver timesharing for S/360 mainframes – TSO under MVS, and VM/CMS, succeeded where TSS largely failed. But TSS hung on for a few more years, sustained by the handful of customers using it, and AT&T decided it was the best base for their mainframe Unix port, and IBM was wiling to support them in that.)
