* The system image size is now calculated as: root size - home size. * New function in `pmb/helpers/other.py`: `folder_size()`, with a testcase. * Instead of copying everything to the system image folder, and deleting the home folder afterwards, do not copy the home folder in the first place. * Added `pmbootstrap -s` to skip generating the initramfs for faster debugging. * Set the default value in the "are you sure, that your partition has at least..." to "y", so we can run `yes '' | pmbootstrap install` to make it run through the whole installation process. * Increase full size to 120%, boot partition gets 15 MB free space now
