+### Complete test sequence (containers)
+
+A fairly decent test suite in this context is to run this
+
+**Subject build is f>=18**
+
+ run nodedistro-f20 reinstall reboot nodedistro-f22 upgrade reboot reinstall reboot
+
+The only thing missing with this is to test bootmanager in the context of a f14 bootCD
+
+### Complete test sequence (mixed vservers+containers)
+
+If on the contrary the build under test is a f14, then run instead this; upgrading a f14 node to f>=18 is not supported due to /vservers being an ext3 filesystem
+
+ run nodedistro-f14 reinstall reboot nodedistro-f22 reinstall reboot upgrade reboot
+
+### Run bootmanager interactively during upgrade
+To deploy experimental bootmanager code:
+
+* Insert breakpoints in the bootmanager code
+* turn on `BREAKPOINT_MODE = True` in `utils.py`
+* `make sync`
+
+Then
+
+ run nodedistro-f22 debug-mode
+ testnodedbg
+
+ cd /tmp/source
+ ./BootManager.py upgrade
+
+Beware that when running installation in debug mode, some stuff like iirc `vgcreate` wait for 'y' for confirmation
