I slightly doubt if I should still use ZFS on my NAS Pi after reading how Stuff actually works with ZFS. At least I got rid of the Default-“Pi” User on the Pi 4B, considering how much of a security risk that would be.
On the Pi3B+ I found out that you should apparently never just dump files on the root of the Filesystem of external Drives, instead make Subfolders which have the right permissions, while the root of the Drive is owned by root only. Never used an ext4 formatted external Drive so far so I did not know that yet.
Making Symlinks on the Pi is quite a hassle though, i seriously need to ln -s that shit on Commandline.
And editing the config.txt in the boot directory is a hassle too, i can’t use the “Save As” Dialogue in Kate to save the File with sudo permissions, because it somehow doesn’t thing that my “greg” User has sudo even though he definitely does have it, and therefore prompts me to enter the password for the “root” User with a dropdown that usually contains all Users as options, but thanks to me removing the “pi” User it doesn’t show shit but “root” anymore. So I have to sudo nano that File.
Also 70°C is a very reasonable setting for the Fan on the PoE HAT on a Pi 4B to spin on, as opposed to the default 60°C, that way the Fan stays silent while the Pi is idle and doesn’t do anything.
Tried out some of the Software that is on the Pis too, it actually has a somewhat decent Music Editing Program, if you look aside that its UI doesn’t adhere to any standards at all, Sonic Pi is actually good for learning.
So far the Pis are still fun to play around with. ^^
