systemd was updated since I made the changes to btrfsmaintenance-refresh.path.
Current  systemd-244-3.1 no longer reloads during boot.

Changes are now for btrfsmaintenance moved from sysconfig to default: 

erlangen:~ # systemd-delta -t overridden 
[OVERRIDDEN] /etc/systemd/system/btrfsmaintenance-refresh.path ���
/usr/lib/systemd/system/btrfsmaintenance-refresh.path

With the above btrfsmaintenance-refresh.service runs only when
/etc/default/btrfsmaintenance actually changes.
