Swapfc path in another partition(?

[YudhaDev]

before that, English is not my first language so please excuse any mistakes.

so today I try to change the path of swapfc into another directory that placed in a partition(ext4). and when I try to start the systemd service I got an error that mentioned PermissionError. I have no clue what to do next except using the default path for now. is it not posibble to do that?

Your issue are python os.mknod trouble , This trouble is your filesystem /mnt/ForSwap can not wirte by systemd .

You can check /mnt/ForSwap directory with ls -alh /mnt/ForSwap and getfacl /mnt/ForSwap command .

Or not you can change your path that path can wirte by systemd.
