Option to shrink result image #36

Closed maitredede closed 5 years ago

maitredede commented 5 years ago

Enlarging the image can be usefull to install apps, but reducing the result image can be also interesting.

For example, you can expand image by 4Gb, do the stuff, and then use a tool like https://github.com/Drewsif/PiShrink to reclaim unused space left, to have a minimal size image (faster to write on SD) that will auto-expand on first boot.

Maybe it can be an option in the config file

This is already an option in the base module. See BASE_IMAGE_RESIZEROOT https://github.com/guysoft/CustomPiOS/blob/devel/src/modules/base/config#L26 Note the way its calculated is image size + x extra space.

You can also set that you want the result image to have a small BASE_IMAGE_RESIZEROOT , but a large building space with BASE_IMAGE_ENLARGEROOT: https://github.com/guysoft/CustomPiOS/blob/devel/src/modules/base/config#L23

We really need this info in the wiki, if anyone wants to write a "module settings" entry.
