Continue Boot On Device Failure
I have a USB hard disk attached to a headless Ubuntu 12.04 server. I recently modified fstab so the drive is mounted on startup. I noticed a few days ago that rebooting this server leaves it in a non-functioning state.
In order to troubleshoot I have to pull the computer off the rack, connect a mouse, monitor, and hard reboot. I noticed a message indicating that device UUID=blahblahblah was not present or was not ready and glancing over, yea the USB drive was not plugged in.
Obviously plugging it in and restarting resolved the problem but the more I think about this the more it irritates me. Why would the booting of a system be halted because some secondary, non-bootable USB device is not present?
Is there a way to tell upstart (or whatever Ubuntu uses e.g. upstart, SysV, systemd) to ignore failures and continue to boot?
