I found a similar issue on Google and it seems that you need to edit the bitcoind.service because it is configured as user: bitcoin and group: bitcoin by default you need to replace it with root if you were currently running it on root user. And also I'm pointing out this setting below and you set it to true which is why the error denied access popup while currently running it on the root user change it to false and try to run it again. "# Deny access to /home, /root and /run/user ProtectHome=true" Here's the source below that I found and hope you can get some idea how to set up bitcoind.service properly. - https://bitcoin.stackexchange.com/questions/118725/bitcoind-service-cant-start-on-mounted-drive Thank you BitMaxz, the problem was the line ProtectHome=true

And at this point, how to fix the problem? those of us who maintain nodes could have the option to accept or not these ordinals? or is it up to the miners?

I have a PC with opensuse leap 15.5 + KDE + bitcoin core 26.0 (/usr/local/bin/bitcoind -rwxr-xr-x 1 root root) the /home/bitcoin/.bitcoin (lrwxrwxrwx 1 bitcoin bitcoin) directory is a symlink to an external disk (/run/media/ibm/BB/BTCbc/ (drwxrwx--- 6 bitcoin bitcoin).
I login with the user ibm which is part of the bitcoin group and I run bitcoind and bitcoin-qt without problems.
I want to run the node as a service from the boot of the PC.
This is the unit/service file's (/etc/systemd/system/bitcoind.service -rwxr--r-- 1 root root) content:

the /home/bitcoin/.bitcoin/bitcoin.conf file use the default configuration, does not point to any datadir other than the default one.
so I try to run the bitcoind service with sudo systemctl start bitcoind.service to check if it runs well before enabling it I get the following error:
Job for bitcoind.service failed because the control process exited with error code.

I don't understand this, since all permissions and ownership are granted, what is systemd denying access to /home/bitcoin/.bitcoin during the execution of bitcoind.service?
SOLVED:
The problem was the following line ProtectHome=true in the Hardening measures section in the bitcoind.service file
I set it to false and now the node starts as a service
thanks to all, especially to BitMaxz who gave me the correct solution.

And never ever download the Bitcoin core from the snap store either

Esta es una advertencia para todos los venezolanos que están comprando equipos BIFTURY B8, estos fueron importados de una manera poco profesional y muy irresponsable por lo que adquirirlos es una loteria, no existe servicio post venta, tampoco la estructura para soporte en el pais.
El mayor problema es que no se adaptan a la caotica red electrica venezolana y por esa razón sus fuentes ELTEK FLATPACK2 48V/3000W suelen dañarse en un promedio de 1 mes incluso bajando el consumo del minero a 48v.
En conclusion, a menos que se disponga de un sistema electrico optimo, con aterramiento adecuado, estabilizadores de voltage y se puedan adquirir las fuentes de poder NO compren este minero, les va a traer muchos problemas.
