Hi All,
On a linux desktop, one way to access your device is to edit the "/etc/fstab" to mount your device permanently so you can access it.
Reading postmarketOS's wiki about fstab, it told you to activate "rc-update" and the localmount service, which is the command:
And to check whether the service is running:
While blkid will return nothing, I use "sudo fdisk -l" to identify the UUID of the SD-Card, which gives:
Therefore, I edit my fstab to looks like the following:
On a reboot it did not give me anything in the folder. Upon the failure, I tried to mount the SDcard by using the mount command, which return error:-
My question is, is there something wrong with what I did or anything that I might not have been aware of?
Cheers.
