pluto automounter: Retry automount in case device driver isn't ready #55

Closed tim-nordell-nimbelink closed 3 years ago

The automounter can try to mount the device prematurely. Catch this kind of error output and retry a few times with some time in between in case we can successfully mount this device.

I've had problems where the automount fails at bootup (around 40% of the time) with a message like the following on stderr from the mount command inside the automounter:

mount: mounting /dev/sda1 on /media/sda1 failed: Device or resource busy

However, adding in a simple retry loop fixes it. I suspect the device node isn't fully ready for traffic at the driver side when it gets enumerated.
