    In Plan 9 the default filesystem is pretty different:

    • all programs are bound to /bin
    • / contains several folder dedicated to the various supported architectures
    • $path usually contains just /bin and .
    • /usr is what /home is to Unix

    In Jehanne I moved all architectures in /arch (to reduce name clashes in /) and renamed /bin in /cmd (since several comands are not really binaries).

    This sort of changes are usually disregarded as bikeshadding, but since I want to build the simplest possible operating system, it’s important to fix them before the OS is actually used.
