[Nss-mysql-users] File system unmount fails when nss_mysql is installed (config in nsswitch.conf)

[Frédéric Trudeau]

I get those error message when rebooting :

Unmounting file system: umount2: Device or ressource busy
umount: /dev/sda3: not mounted
umount: /usr: Illegal seek
INIT: no more processes left in this runlevel

Then, I got to manually shotdown the computer.

Here are my fstab entries :

I have no idea what could cause this, and this is a major issue, not being
able to reboot the computer remotelly.

Thanks for any help.
