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

Prepare a micro-sd-card using the commands:

  • sudo zypper install rpi-imager # or apt
  • rpi-imager

Configure OS

  • Add your external disk to fstab (note the auto, nofail, exec flags, use blkid or gparted 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  0  3
 UUID="1941...-bf8d-...4476"	/var/berrydisk	ext4	auto,nofail,noatime,async,suid,dev,rw,nouser,exec  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
  • for the right keyboard, configure via raspbi-config;
 for the R-go Split keyboard choose Generic-105-key-PC,
 German no-dead-keys, Right Alt as AltGr, no Compose Key, no Ctrl-Alt-Del. 
 Eventually you have to create your own .Xmodmap file and replace the preconfigured keymaps,
