!Prepare PI5
I followed more or less [StepByStep Instructions by Harald Kreuzer|https://www.haraldkreuzer.net/aktuelles/logitech-media-server-auf-dem-raspberry-pi-4b-mit-5-zoll-display-installieren] to install on my PI5

Keep updated, for a major update (debian) you need to reinstall
{{{
> sudo apt update
> sudo apt -y full-upgrade
> sudo apt -y clean
> sudo apt -y autoremove
}}}
Automatic updates, see [elektronik-kompendium.de|https://www.elektronik-kompendium.de/sites/raspberry-pi/2002101.htm]

!Display / Lite to Desktop
Change Raspberry OS lite to [desktop|https://raspberrytips.com/upgrade-raspbian-lite-to-desktop/]. \\
If you need just a console via HDMI, install default desktop for raspberry.\\
This uses wayland for debaian bookworm and PIXEL for older versions.
{{{
> sudo apt install raspberrypi-ui-mods
> sudo raspi-config > System Options > S5 Boot / Auto Login > B3 or B4 to use desktop #use to switch to desktp mode
}}}
The console display is controlled via [cmdline.txt|https://www.raspberrypi.com/documentation/computers/configuration.html#set-the-kms-display-mode].\\
Notes:
* the cmdline.txt must have ONE line only, keep what is in there and append with SPACE as separator
* you can have "video=" only on the first HDMI port (does not work on second)
{{{
> kmsprint | grep Connector # find out which hdmi port is used, you need HDMI-A-1
> sudo vi /boot/firmware/cmdline.txt # edit as ONE line !
append in first line " video=HDMI-A-1:1920x1080M@60,rotate=90" # rotation happens anti-clockwise
}}}

As my case offers a PCIe M.2 NVMe slot I added a SSD 4TB Lexar NM790 M.2 2280 PCIe. This had frequently "input/output error", which could be resolved via reboot only. There seesm to be an issue at the kernel, see [here|https://forum.proxmox.com/threads/lexar-nm790-2tb.134293/]
Anyway, I returned this device and bought a "4TB Samsung 990 PRO M.2 2280 PCIe 4.0 x4 3D-NAND TLC (MZ-V9P4T0BW)".

!minidlna does not stream
Do not use symbolic links in your media drive, content there will be listed, but not displayed!
! no diskspace on mmcblk0p2 (SD Card extension partition, e.g. not the boot one)
{{{
> sudo lsblk -f # check partition usage
> df # check where partition is used
> sudo du -h -d 1 # check all folder's usage in current folder
}}}
Solution: with du I could identify that minidlna log captured everything at /var/log/minidlna
