Something interesting about Crostini is that it uses 9p to bridge filesystems, just like WSL2. It seems that 9p has "cracked the code" on bridging filesystems over virtual machines and differing operating systems in a way that other options never seemed to do quite as seamlessly, which I find rather interesting. Maybe it's because it comes with less baggage than CIFS? Easier to extend? Less complex than NFSv4? I'd love some commentary on this.
The filesystem bridging between Crostini, the rest of ChromeOS, and Google Drive is brilliant. It also transparently integrates SSHFS into the filesystem and the file browser.
