How to umount a wpa_supplicant _netdev device at shutdown with systemd ?

[Javier Barroso]

Hello,

I'm having a problem with a curlftpfs mount at fstab.

I reported a bug to Debian and a bug to Systemd:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=769186
https://bugs.freedesktop.org/show_bug.cgi?id=86707

At Systemd Bugtracker they tell me about wpa_supplicant.service should
have a Before dependency on network.target

That solution did not work to me

Somebody have a wpa_supplicant _netdev device on /etc/fstab and
running systemd the system won't hang on shutdown ?

My problem is that wpa_supplicant deauthenticate to my AP before
curlftpfs can umount the device.

Can you help me ?

Thank you
