mount command does not actually mount the drive on raspberry pi OS lite

[Roaders]

I have setup a new raspberry pi lite OS specifically to test usbmount (so it's a brand new image downloaded today and there is very little else on the system). I am having quite a few issues getting usbmount to work.

Currently I have the latest version from apt-get (0.0.22) isntalled and I am the closest that I have been to getting usbmount to work. I currently get this output:

as you can see it runs the mount command - BUT the drive is not mounted. If I run the command myself (with sudo) then the drive is mounted fine. I am using the normal pi user. I am not sure what user usbmount uses.

I have also cloned the repo and built 0.0.24 locally and tried that. That does not work as well and doesn't run the mount command. I get:

I'm getting the same issue (Ubuntu 20.04 using the distributed version). But if I manually run "sudo mount..." (and copy the mount command from the log) it DOES mount. So the command is right.

I also see "FAT-fs (sda): Volume was not properly unmounted. Some data may be corrupt. Please run fsck." in the log, which I don't get when I run the mount manually.

I'm wondering if it's mounting and then unmounting? Or if there is some other mount error that isn't being logged?

[jaccc]

it is caused by systemd which is using private mount

thanks, @jaccc -- is there a fix/workaround?

[derekatkins]

Strangely, even though the "mount" is being private, the /var/run/usbmount symlink gets created no problem...

[derekatkins]

Aha, looks like Issue #25 explains the issue and the fact that the "native" usbmount is STILL too old!

Yes, I should have updated this. I did manage to get it working by cloning, building and installing the latest version from Github. I think that the issue I had initially was just that I had the wrong file system on the SD card.
