Bug#1010756: davfs2: should allow non-root users to mount a davfs file system (like sshfs)

[Vincent Lefevre]

Package: davfs2
Version: 1.6.1-1
Severity: normal
Tags: upstream

When I installed davfs2, a dialog box said that it needed to be
setuid to allow non-root users to mount a davfs file system.
Moreover, mount.davfs also needs an entry in /etc/fstab, otherwise
one gets an error "no entry for ... found in /etc/fstab".

It should be fixed to make these things unneeded. As a comparison,
sshfs doesn't need all that. I don't see what could be different
between sshfs and davfs2 concerning permissions (e.g. both are
based on FUSE).
