OpenBSD 6.7 microSD card image

[krjdev]

I'm curious on how did you created the image. Did you created a microsd per https://ftp.openbsd.org/pub/OpenBSD/6.7/...TALL.arm64 instructions, then you installed it in an USB, then created an image from that USB?
I want to give OpenBSD a try on my regular pinebook 1080p so if you have the steps it would be helpful
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. 


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.
