_netdev with wpa_supplicant dependency doesn't work at shutdown
I'm trying to solve my own reported bug 
When I add a curlfs fstab entry via wifi (wpa_supplicant), it get
mount at boot, but it does not umount when system is halting / at
shutdown. Wpa_supplicant stop before than curlftpfs umount the mount
I have been playing with "After / Before /Requires" parameters both,
but I'm getting tired .. I'm not able to make it work :(
What I have tried:
1. Modify fstab-generator , so xx.mount depends on :
2. Modify wpa_supplicant.service, so depends on:
Do you have any hint about this issue ? How can I get it working ?
How can I say to systemd about not stop wpa_supplicant until xx.mount
is umounted ??
Thank you very much
