Fedora: Can't find microstack.rabbitmqctl

[Pen Gale]

The MicroStack snap can be installed on Fedora, but the .init fails with an error message that seems to indicate that microstack is not in the path in the snap environment.

To reproduce, spin up a Fedora machine (I used the Fedora 31 Server cloud image, and spinning it up using MicroStack), and do:

    sudo dnf install kernel-modules -y
    sudo dnf install snapd -y
    sudo ln -s /var/lib/snapd/snap /snap
    sudo microstack.init -- auto

I'll post the full error in the comments below.

The error:

Interestingly, I get further if I open a shell in the snap environment and run microstack_init from there (though note that there are some missing libs that will probably cause mischief):

[fedora@fedora ~]$ sudo snap run --shell microstack.init
