Accessing nodes' filesystems

With tpi it's possible to access filesystems of nodes by booting them as a Mass Storage Device (MSD).

1. Execute a command with a desired node number:
   tpi advanced msd --node 1
2. Wait for the device to reboot, which should take around 10 seconds.
3. Create a directory for mounting, if needed:
   mkdir /mnt/raspios
4. Mount one or more desired partitions:
   mount /dev/sda1 /mnt/raspios
5. Perform any applicable read or write operations:
   vi /mnt/raspios/config.txt
6. Unmount the device and reboot:
   umount /dev/sda1
tpi power off -n 1
tpi power on -n 1
