davfs2 problem

Hi!

I have ARMBIAN 5.31 on my Banana Pi m1 and need some help.

Early I used wheezy and mount webdav disk with davfs2 in fstab, but after I installed jessie fstab dont mount any davfs2 disk.

Besides I have another problem: I use davfs2 to backup some video and photos to cloud storage throw webdav, and I have mistakes on large files (files much bigger then free space in /var/cache). Davfs2 send files in cache folder first (/var/cache/davfs2 by default) and then to webdav disk, so I have to use another disk with enough free space (sda1 in my case). When I was on wheezy I just point cache dir to sda in dafs2.config (cache_dir option) and all be OK, but in jessie I get error:

mount -t davfs -o _netdev webdav.yandex.ru /hdd/bak/yadisk
/sbin/mount.davfs: can't open cache directory /hdd/tmp/davfs2
