I'm using an external drive with BackupPC on CentOS 7. I currently have a mount entry like this in fstab: /dev/disk/by-label/backuppc4 /var/lib/BackupPC ext4 noauto,rw 0 0 This means I must manually mount the drive and then start the backuppc service. Is there a way to set up hotplugging so that the drive is mounted if present at boot time but doesn't stop the boot if it's not present or otherwise fails? I see the fstab nofail option. Will that do what I want? Is there a way to set up the backuppc service (through systemd) so that it starts if and only if the drive is present, or starts if the drive is plugged in later? --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
