On Proxmox I recent updated a debian container - and when I rebooted it it wouldn't start!
In the browser I could see an error but no details.
So I tried launching from the browser as
pct start 103
Only to receive the error
Failed to run lxc.hook.pre-start for container "103"
But when I ran the verbose (debug version) of pct start
I could see that a mount point didn't exist!
