Hi all, Hoping someone might have a good technique for this situation: I have a laptop with a docking station and in the expansion bay of the dock, I have a second hard drive, which I have configured as /dev/ad4s1d and mount it to /hd2 Normally on workstations with a 2nd drive, I'll just put another line in fstab and it will mount at each boot. But because this is a laptop, and will be pulled off the dock when I'm on the road, I can't have that, because FreeBSD will scream into single user mode if that partition isn't there. I could put a 'noauto' switch into fstab, but that still leaves me with the problem: The reason for the second drive is for backups: I want to run rsnapshot to take regular snapshots of my primary drive filesystems to the 2nd drive, and rsnapshot runs as a cron job. Now rnsnapshot is smart enough to know not to create the snapshot root if the mount isn't there, but while I am docked, I'll have to remember to manually mount the second drive. If I forget (which I'm apt to do), then no backups :( What I'm looking for is a script or something that will mount /dev/ad4s1d to /hd2 automatically when it's present, but ignore it when it's not, and if possible to unmount it gracefully on shutdown. I looked at amd automounting, but that seems to be a bit overkill (I really don't like the idea of adding NFS et.al. if I can avoid it). Any ideas? Cheers, DW
