LGTM syntactically!

[brandond]

nit: do we need to check for suse again when we're already in a suse-specific block?

Posting here just for tracking until other issues get created.

Single node install is good - SLES 15SP4
Single node upgrade on existing install is good - SLES 15SP4

Current issues noticed in testing:

Fedora:

1. Not registering channel properly in that it is also trying to pull from stable. I believe this is due to line 489 in the currently live install script that has not been changed in this PR:

...
Added:
  k3s-selinux-1.3-4.coreos.noarch
Changes queued for next boot. Run "systemctl reboot" to start a reboot
[WARN]  Failed to find the k3s-selinux policy, please install:
    rpm-ostree install -y container-selinux
    rpm-ostree install -y https://rpm-testing.rancher.io/k3s/testing/common/coreos/noarch/k3s-selinux-1.2-2.coreos.noarch.rpm
...

2. Shouldn't start k3s automatically. This should be more like the transactional-update
3. Uninstall needs to take rpm-ostree into account as well

SLE Micro:

1. Failed to install k3s-selinux:
