Current livepatch implementation supports late patching of modules when they are loaded (and unpatching when unloaded). It has caused headaches and LPC microconference is a good opportunity to discuss the future of the feature. There were attempt to deny the module removal. Introduction of patch module dependencies could also simplify the code and issue a lot. On the other hand, such solutions could make livepatch less flexible. It is necessary to weigh their advantages and downsides properly.
