I think we'll need md-raid-utilities/mdadm#14 or we'll get segfaults at runtime:

Monitor.c: In function ‘Monitor’:
Monitor.c:257:34: warning: implicit declaration of function ‘basename’ [-Wimplicit-function-declaration]
  257 |                                  basename(mdlist->devname));
      |                                  ^~~~~~~~
