When you flashed a “.wic”-file your system will only have one partition
with almost no space. To make the filesystem usable, we provide an
auto-partitioning tool called
- Run the script in interactive mode.
- Press enter without entering values on all the steps.
nmhw-auto-part.sh [OPTION] 'devicename' 'size' 'mode' 'size'
- device to use: e.g. /dev/sdb /dev/mmcblk1
- size of the first partition in MB (set 0 to keep current size)
- ‘data’ or ‘overlay’; type of partition to append
- size of the appended partition in MB (set to 0 to fill)
-i interactive mode -h help
You can either pass the four arguments ‘devicename’, ‘size’, ‘mode’ and ‘size’ or one option.
nmhw-auto-part /dev/mmcblk1 1024 overlay 0
The same as running the recommended settings.
How to undo the partitioning¶
- Delete Partition information
rm -r /etc/nmhw-auto-part reboot parted /dev/mmcblk1 rm 2
- Rerun the autopartition script.
Note: The first partition will keep its size.
Files in /etc¶
- This is an empty file. It indicates to the init script that it needs to mount an overlay.
- This file contains the path of the device, which serves as the data partition. It indicates to the init script that it needs to mount the data partition.
