Q. Did the operator change anything to the system before it failed ?
A. Yes. He created a permanent automatic mount entry in fstab for
a removable device which is not always present. BIG mistake. At
least when you do that, add the "nofail" option and use an
identifier which is less volatile than the device file.
Solution : revert the change. No need to reinstall.
If could've, would've <smile>
When I noticed that systemd was having problems with the destination
disk I discovered the wall wart was unplugged.
If my _only_ problem was the fstab entry, shouldn't my sequence of:
1. power down laptop
2. plug in wall wart
3. power up laptop to reboot
have worked?
Maybe. Maybe not. You used the device name /dev/sd* in fstab, but this
is volatile and may change the next time you plug in the same device.
Bottom line : do not use volatile device names in fstab. Use UUID, label
or whatever persistent identifier available in /dev/disk instead.
