/etc/fstab contains duplicate lines
My VPS gave errors like systemd-fstab-generator[xxxx]: Failed to create mount unit file /run/systemd/generator/var-www-clients-client1-web1-log-client\x2dbv.nl.mount, as it already exists. Duplicate entry in /etc/fstab?
When I checked my /etc/fstab file it contained indeed duplicate lines for some domains, not all. Some of the lines are actually just duplicates but some lines have none bind,nobootwait 0 0 or none bind,nofail 0 0 in the end.
Like suggested by #5131 (closed) I have deleted the duplicate nobootwait lines and all remaining duplicate lines.
