Its autofs is configured to mount harddrives labeled npg-daily-XX onto /mnt/npg-daily/XX where XX is a label number. Its backup script needs further investigation to determine exactly how it works.

			As of Feb. 15, 2015 Lentil is mounted with the following which will last us awhile:
			*/dev/sdd1 mounted at /mnt/npg-daily/51; A filled 2TB hard drive
			*/dev/sda1 mounted at /mnt/npg-daily/52; A 4TB hard drive
			*/dev/sdb1 mounted at /mnt/npg-daily/53; A 4TB hard drive
			*/dev/sdb1 as the root file system. Don't hot swap this.

			== Authentication ==
			Lentil authenticates against the LDAP server running on Einstein, by connecting to einstein.farm.physucs.unh.edu using sssd.
			Previously, Lentil went on the UNH network to einstein.unh.edu, but this is blocked (I think by ip-tables). The farm network is the better choice anyhow.

			If this appears while booting:
			request_module: runaway loop modprobe binfmt-464c
			This is an indication that a drive (in the supermicro hot swap bay) is plugged in that
			can't be mounted, like a drive with a software raid setup on it, so just pull the drive
			and reboot and it should boot properly.

			== If Lentil isn't sending e-mails ==
			Sometimes after a reboot Lentil won't send its regular e-mail reports. To fix this you simply need to restart sendmail. Be aware that it has saved all of those messages it didn't send, and once sendmail is working you'll get all of them at once.
