i've got a vhost running ubuntu 12.10.
i installed davfs2 and edited my /etc/fstab file like the following:
https://somedomain.de/webdav.php/somefolder/ /mnt/s02 davfs defaults 0 0
now mounting this using mount -a works fine. also if i type reboot after connecting using ssh on my vhost as root user, my drive gets mounted correctly.
but using the web-backend of my provider (digitalocean) and clicking "reboot" there, i get an error after my machine starts up:

any ideas why this is happening and how to fix this?
