I want to give OpenBSD a try on my regular pinebook 1080p so if you have the steps it would be helpful Smile
Thanks!

Sorry, for my late response. Sure...

I used a very dirty solution to create the image. But should also work with other OS'es.  Big Grin


Step 1:

Zero-out a microSD card. This step isn't necessary, but it results in a smaller compressed image.


Code:
$ dd if=/dev/zero of=/dev/sdx bs=1024

Step 2:

Install OpenBSD with a custom partition layout. For example: Make a partition with 3GiB and remember the size.


Step 3:

Simple copy the image from the microSD card with a greater size, as the created partition.


Code:
$ dd if=/dev/sdx of=/path/to/image.img count=3.5G


Step 4:

Compress the image.

Code:
$ xz -k /path/to/image.img


That's all. Quick and dirty! Okay, could be improved, but works. Big Grin
