Hi,
I have an entry in the fstab to mount an NFS share via IPv6. For
unknown reasons, the entry is being ignored on boot, so after booting,
I have to log in as root and do a 'mount -a' which mounts the share

The entry in the fstab looks like this:
[fd53::11]:/srv/example
1.1,credentials=,rw,GID=1000,uid=1000,noauto,x-systemd.automount
It's a matter of edit-reboot-test cycles with a consistent and complete
test protocol.

The device is a usb-harddrive, formatted with ext4. It is connected to an usb

So it is plasma5 which is mounting the device.

When doing pipelines involving 'dd bs=1M ...', I have also found

Many time I found it necessary to put a sleep between operations
Several decades ago I was taught to type sync and then type sync again before
