@2bluesc I launched it on my ext4 filesystem.

EDIT: The complete error log:

bmaptool: ERROR: An error occurred, here is the traceback:

@Distag this is more of an issue with your filesystem.

I used bmap-tools on btrfs almost daily without issue. What file system are using? Perhaps something like vfat?

Hello, It seems does not work correctly with the current archlinux.

truncate --size=1G disk.ext4 #create a 1G sparse file
mkfs.ext4 disk.ext4
bmaptool create disk.ext4 > test.bmap

It gives this error:

bmaptool: ERROR: cannot generate bmap for file 'disk.ext4': the file-system does not support "SEEK_HOLE" and "SEEK_DATA" but only provides a stub implementation

Actually python-setuptools should be part of depends, not makedepends, as it's required at runtime.

Easy to verify:

$ sudo pacman -R python-setuptools
$ bmaptool create some-image.img > tmp.bmap
Traceback (most recent call last):
  File "/usr/bin/bmaptool", line 6, in <module>
    from pkg_resources import load_entry_point
ModuleNotFoundError: No module named 'pkg_resources'

This is mentioned at https://wiki.archlinux.org/index.php/Python_package_guidelines#setuptools

Why don't you use the official tar (ftp) instead? ftp://ftp.infradead.org/pub/bmap-tools/
