Set up an MS App password for rclone on https://mysignins.microsoft.com/security-info

sudo apt-get install rclone

mkdir -p ~/.config/rclone/
vi ~/.config/rclone/rclone.conf

~/.config/rclone/rclone.conf

[whatevername]
type = webdav
url = https://domainname.sharepoint.com/sites/sitename
vendor = sharepoint
user = firstname.lastname@example.com
pass = xxxx

rclone config
#edit existing site and add the app password

Mount using the following, where “whatevername” is the name of the sharepoint site and “~/sharepoint/whatevername” is the desired mount point:

rclone --vfs-cache-mode writes mount whatevername: ~/sharepoint/whatevername

If this works, run it in daemon mode:

rclone --vfs-cache-mode writes mount whatevername: ~/sharepoint/whatevername --daemon

To stop the mount, use:

fusermount -u /path/to/local/mount
#or
fusermount -uz /path/to/local/mount

to use in fstab, create wrapper using:

sudo ln -s /usr/bin/rclone /sbin/mount.rclone

then it can be used in fstab like:

whatevername: /path/to/mount/point rclone user,rw,noauto,nofail,_netdev,x-systemd.automount,args2env,vfs_cache_mode=writes,rc.config=/etc/rclone.conf,cache_dir=/var/cache/rclone 0 0

or better use rclonefspy script

Then use

For troubleshooting use:

journalctl -b | grep rclone

Fuse config required for user systemd service:

/etc/fuse.conf

# Allow non-root users to specify the allow_other or allow_root mount options.
user_allow_other

rclone@.service

# User service for Rclone mounting
#
# Place in ~/.config/systemd/user/
# File must include the '@' (ex rclone@.service)
# As your normal user, run 
#   systemctl --user daemon-reload
# You can now start/enable each remote by using rclone@<remote>
#   systemctl --user enable rclone@dropbox
#   systemctl --user start rclone@dropbox
