i create a image with disk size 200GiB, i try export image and import tvm file on same device ,the device remaining disk size must be less than 200Gib , it work.
but if i send tvm file to other device who disk size less than 200Gib, it will be error
i don't know how does tart deal with the problem of sparse files actually occupying the disk when decompressing them?

With the same device you already have the image locally so Apple File Systems takes care of figuring out the duplication and saving up the actual physical space. On other device you'll need space for both the archive and 200GB of the image.

i never try small size image import and export ,i will try it .
is it certain that if the remaining disk size of the host is larger than the original size of the image, compression and decompression can run normally?
and does a lower version of macos(12.5) not need other support to run a higher version of macos(14.0)?

ok,thanks! i will try make disk image smaller

other question, i create big size image cuz i create image by tart‘s '--from-ipsw' flag, not use packer plugin , packer plugin will removes recovery partition.
but if dont remove recover partition, i cant patch disk size to bigger on runtime , any suggestion for this ?
or can you tell me how to delete the recovery partition myself? I need documentation on this
