Unable to re-run system-reinstall-bootc after failure

[ckyrouac]

If system-reinstall-bootc progresses to the point where it creates the default stateroot, then the following run results in:

ERROR Installing to filesystem: Creating ostree deployment: Cannot redeploy over extant stateroot default

An example is if the install fails due to the disk space check, the user frees up enough space for the install, then this error will be hit.

The workaround is to rm -rf /ostree after the failure, however I think the state should be cleaned up on failure.

Yes this is a pain. I think what we're missing here is that we should just check that we're not redeploying over the booted stateroot; we can completely safely operate on a non-booted stateroot.
