-_dump_boot_ and _write_boot_ are the default method of unpacking/repacking, but for more granular control, or omitting ramdisk changes entirely ("OG AK" mode), these can be separated into _split_boot; unpack_ramdisk_ and _repack_ramdisk; flash_boot_ respectively. _flash_generic_ can be used to flash an image to the corresponding partition. It is automatically included for dtbo and vendor_dlkm in _write_boot_ but can be called separately if using "OG AK" mode or creating a simple partition flashing only zip.

 Multi-partition zips can be created by removing the ramdisk and patch folders from the zip and including instead "-files" folders named for the partition (without slot suffix), e.g. boot-files + recovery-files, or kernel-files + ramdisk-files (on some Treble devices). These then contain Image.gz, and ramdisk, patch, etc. subfolders for each partition. To setup for the next partition, simply set `block=` (without slot suffix) and `ramdisk_compression=` for the new target partition and use the _reset_ak_ command.
