This breaks compilation:

main.c: In function ‘sd_notify_status’:
main.c:184:2: error: enumeration value ‘DAEMON_STATUS_SIZE’ not handled
in switch [-Werror=switch]
  switch (state) {
  ^~~~~~

Please avoid introducing DAEMON_STATUS_SIZE.

This would be fixed by your patch 2 because it removes the switch
statement, but no patch in a series should break compilation, to 
allow future bisections.

I have to withdraw my "Reviewed-by: for the time being, sorry.
