I think you have raised an excellent point, which also led me to reconsider my thoughts. Truly, when you argue with my definition, a Fedora workstation in an enterprise where an end user cannot install apps shouldn't be considered Linux, because the end user isn't able to install apps on it. A few of the points you raised (e.g. LXD) I haven't even known existed. But I e.g. use Fedora Silverblue, and with Toolbox you can emulate a Ubuntu distro. Should then Silverblue be not considered a Linux distro because it doesn't offer installing native packages by itself? That would be a risky argument to make. So in the end, I thank you for the points you raised. You have led me to reconsider the topic. I especially didn't knew that Crostini was based on a Linux stack, I always thought that it was a side-loaded emulator which "replaced" ChromeOS - which even isn't logical, as I now see. So thank you, I learned something new from today and will pay more attention to see ChromeOS not as something distinct from Linux, but just as a distro with a "Google-y touch" on it. Especially now with ChromeFlex, where you can install it on every PC with a processor => toaster, it has truly become a Linux distro.
