HW

• Attach the cables
• Attach an external disk (Note: This might get booted twice at every system start)
• If the SD card gets corrupted, repair it with e2fsck or dosfsck:

 linux:/dev # dosfsck -a mmcblk0p6
 fsck.fat 4.1 (2017-01-24)
 0x41: Dirty bit is set. Fs was not properly unmounted and some data may be corrupt.
  Automatically removing dirty bit.
 Performing changes.
 mmcblk0p6: 211 files, 45710/139106 clusters

Setup OS

• Format an micro SD card to FAT (the preinstalled exFAT is possibly not recognized)
• Unzip the NOOBS installer

Configure OS

• Add your external disk to fstab (note the auto, nofail, exec flags, use blkid to find the UUID):

 proc            /proc           proc    defaults          0       0
 /dev/mmcblk0p6  /boot           vfat    defaults          0       2
 /dev/mmcblk0p7  /               ext4    defaults,noatime  0       1
 UUID="47be...-350a-...9cfb"	/home/berrydisk	ext4	auto,nofail,noatime,async,suid,dev,rw,nouser,exec	03
 UUID="1941...-bf8d-...4476"	/var/berrydisk	ext4	auto,nofail,noatime,async,suid,dev,rw,nouser	0	3

• define users

 adduser <user> # adds a user and a group and a home directory
 adduser <user> sudo # adds an existing user to the group sudo
 deluser --remove-home <user> # deletes a user - do this for pi

• use the same user ids as on the other linuxes where you attach the external disks

• in /etc/passwd change the homedirectory of a user to /home/berrydisk/...

• Make user selectable at boot:

 sudo raspi-config
