sparse allocation ("holes"), so that uninitialized space in the disk
images does not occupy actual space. You may need to tell `tar` to
preserve this sparse allocation when you extract, e.g. with the `-S`
option.
The current

is 143510751 bytes, and its sha256sum is

V4 corrects ACL problems in the Rev19 and Rev24 images.
V3 removes additional junk, and rebuilds the disk images as 600 MB
