2020-04-06bootstrap: Add missing reference to send port between tasksSamuel Thibault
When giving the port to a bootstrap task to another bootstrap task, we need to add a reference. This shows up on error-cleanup (e.g. when forgetting to define the root). * kern/bootstrap.c (boot_script_insert_task_port): Call ipc_port_make_send on `task''s itk_sself.
