Microstack install on Fedora 33

Hi all,

Has anyone successfully installed and run microstack snap on Fedora 33 or any Fedora version?

I can install no problem with sudo snap install microstack --devmode --beta but running init fails.

$ sudo microstack init --auto --control

And the error in journalctl -xe is:

From what I can figure out this is because ovs-ctl is run with /bin/sh

$ head -n 1 /snap/microstack/233/usr/local/share/openvswitch/scripts/ovs-ctl
#! /bin/sh

but inside the snap /bin/sh is a symlink to dash

$ sudo snap run --shell microstack
WARNING: cgroup v2 is not fully supported yet, proceeding with partial confinement
bash-5.0# ls -al /bin/sh
lrwxrwxrwx. 1 root root 4 Jul 18  2019 /bin/sh -> dash

And sourcing /etc/init.d/functions with dash shell does indeed result in Syntax error: "(" unexpected (expecting "done").

Is there a way around this? Perhaps to change /bin/sh -> bash to support Fedora?

To me this looks like an issue with snap services on Fedora rather than specific to microstack. Happy to file bug/issue elsewhere if this is not the right place.
