Steps to restore RMS headless (RasPi w/o display) setup on your Linux workstation:
1. create fresh RMS image on a new SD card: unzip -p "RMS_RPi4_image_20210626.zip" | dd of=/dev/mmcblk0 bs=4M status=progress conv=fsync
2. mount the card (e.g. via GNOME Files) and update the hostname in rootfs on the card etc/hostname and etc/hosts (line for 127.0.1.1	<hostname>)
3. if using a static IP address, update static * lines under "interface eth0" in etc/dhcpcd.conf
4. update home/pi/.ssh/authorized_keys with your ssh pubkey from your workstation
5. copy RMS ssh identity from RMS backup: cp id_rsa id_rsa.pub home/pi/.ssh/; chmod 400 home/pi/.ssh/id_rsa*
6. copy RMS config from RMS backup: cp .config platepar_cmn2010.cal mask.bmp home/pi/source/RMS/
7. update .config device line for RasPi4:
-device: rtspsrc location=rtsp://CAMERA.IP:554/user=admin&password=&channel=1&stream=0.sdp ! rtpjitterbuffer ! rtph264depay ! queue ! h264parse ! omxh264dec ! queue ! videoconvert ! appsink sync=1 ; device id
+device: rtsp://CAMERA.IP:554/user=admin&password=&channel=1&stream=0.sdp ; device id
+force_v4l2: false
8. echo 1 > home/pi/.rmsautorunflag
9. in card's bootfs append to cmdline.txt:
net.ifnames=0 init=/usr/lib/raspi-config/init_resize.sh
Unmount the new SD card from your workstation, put it in RasPi4 and boot, after resizing it should reboot again and start RMS automatically.
